Performance chip

I am looking for information on best choice for a performance computer chip for my 2007 chevy 3500 hd 6.0L truck. I have read other threads involving diesels, but not too much on gas engines. I am looking for better towing performance on my truck. Anybody have any experience or reccommendations would greatly be appreciated.

Thanks

Mark

Gasser chips are worthless. I had one for my 98 chevy 5.7 and it didn't do anything for me. I wouldn't waste my money.

I would try the Triple dog gas downloader since they have the try before you buy then you can see if that makes a difference. That's the cheapest way to find out. If it does then buy one on ebay. There are lots of different programmers out there I had the Jet performance on my gasser and I didn't think it made much of a difference as far as fuel milage, but did give it more power. Some of the performance places around here have demo models to try first to see if it's what you want, but they all do things a little different some shift harder, some get dtc codes and clear engine lights for you some are just for power. As you can see by my sig I'm partial to bullydog but everybody likes something different. Go to the speed shop that you trust and ask them what they think.

HP gains for gassers are very small ~ maybe 20 HP.
You'll have to run premium fuel you may not even feel the difference.
If you go ahead with this mod, please let us know how it performs.

I just purchased one for my diesel, and the local dealer said I should see a significant gain in mpg towing (I don't care about the performance setting, as I use my F-250 almost exclusively for towing). He also said he would sell them for gassers, but he kinda discouraged it because of what others have said---the increase in hp or mpg was minimal. I have not used mine yet, but will do so for a trip covering about 800 miles this week. I shall see. If I don't see a difference, there will be one for sale on Craig's List or Ebay---cheap!!!

What programmer did you purchase?

Myth #1, you will not see a gain in towing MPG. Power, yes. MPG, no. If you do, it's not significant.

I got my chip for better towing performance and improved shifting. MPG wasn't a thought. I got 10-11mpg before when stock and I still get the same now. The only time the real gains come into play are on hills or acceleration. When you are flat landing it, the fueling is about the same stock or in a tow program. The difference being a tune can drop the fuel in these cruising RPMs to help MPG whereas you are stuck in a stock tune with what they give you.

Well I went with a Superchip Flaspaq tuner. I ordered it last week. Have not received it as of yet. I will post a update once I receive it and see the what I hope is better performance in towing. I already get horrible MPG, I have been averaging 8-9 mpg towing currently. I really wanted it for better power on hills and stuff.
I will update shortly..

Thanks for all the advice.

Cortex Superchip

Actually, Flashpaq Superchip, I hooked it up yesterday. I was suprised, The performance tune had very good results. I plan on pulling the cat next weekend, So I will see what the tow tune results are.

If you use a chip do you have to do other mods such as cold air intake and exhaust ?
I had an 2006 Silverado with the 6.0 with 3.73s, put a Brute Force cold air intake and I was able to achieve higher horsepower quicker,(and in sounded cooler) as we know the Vortec only creates horsepower at 4000+ RPMs. I did get about 20% better MPG. From 10MPG to 12MPG. Bought off E-bay

Actually, they recommended that the chip/tuner be placed on a stock set up. But I have read that people add on the cold air intake to increase there gains. That will be my next step if I am not satisfied with the tuner alone. If the towing gains are as good as I experienced with the performace set up I might be ok as is.

If you run a programmer on the diesels you just have to watch what you run it on. Tow mode on pretty much any of them won't hurt anything but once you go above that you take the risk of the EGT's getting to high if you have a stock set up on the truck the back pressure from the cat and the stock exhaust create alot of heat at the turbo. As long as your not hot rodding along all the time you should be fine. Some programmers run higher EGT's than others even on the tow mode it's just the way they program them.

Just got back from a quick trip down to Florida, and was very satisfied with the Cortex programmer set for tow/haul mode. I averaged 11.9 overall, and I normally get 12.3, BUT, on this trip I never had the tires on any interstate highways. It was mostly state roads, uphill and downhill, and several towns, including straight through the middle of Columbus, Ga., with a gadzillion red lights. Be interesting to see how it does on flat out interstate, which is what I usually travel. Big difference on the down/up shifting on the hills---not near as much as usual.

Mark, do you have an update on this? Looking for the same performance, wondering if it's worth it!

I have been more than satisfied with the performance gains with the superchip. I honestly think the mileage gains with normal driving with tune on fuel ecomomy setting has resulted in my ROI already. I gained about 4-5MPG while not pulling the cat. But while towing I see positive gains on torque that help the truck pull the cat much better. All in all I think it was well worth it. Last mont I headed to PA and encountered some hilly roads and performance was much better taking those hills.

Let me know how you make if you chose to go with a chip.

grover, have you had any problems with your monitor ? mine keeps going out and coming back on while driving and sometime when i start the truck, it freezes on the bullydog logo....i have to then reprogram it to my truck...i've rebooted the thing, updated it and it still does it. even the dealer who put it in is stumped, he called tech and they said it was a connection and not the monitor...we rechecked all connections..same thing.. any ideas ?

I have the Flashpaq SuperChip. I use it in the tow safe mode for pulling my WC. I have no other mods on my Ford 250 diesel. I have found that the improved horsepower and shifting is great...however, I've notice no increase in full economy. The extra horses give it that little extra "hump"!!! Be sure and keep the programmer updated...you can do this free off the internet.
I've read, and it seems to be true, that you do not need to chip/program your truck until after 15,000 miles.
I like the Superchip I have...only disappointment is no increase in full economy.

i gained almost 5 mpg with my triple dog while empty and 3 while towing.

Isimar,

I had that happen to my monitor a few times I ended up redoing the connection at the fuse box under the hood ( the one that piggy backs the fuse) haven't had any troubles since. Make sure they they have it on the correct fuse. Does everything else seem to work correctly besides not coming on once in a while?

when driving, it still goes off and on...once in a while when i go to start up, it freezes on the logo and i have to toggle it to assign it to the correct truck...and it comes on, on extremme, which i didn't notice until i went to take off and the shift was hard.
looks like bullydog is going to send a new monitor and we'll see what happens then.

Sweet hopefully that'll take care of the problem, The only other thing that I can think of is were they ran the power wire through the firewall they might have cut it and its grounding out somewhere. Good luck

had to send the whole shootin match back to bullydog...both batteries were being drained within 4 days....we took the monitor out first(and tried it) and it still happened....then we took out the programmer and took it to the dealer where they let it set for 6 days without a 2 point drop in voltage.....
i've never heard of a programmer killing batteries before...have you grover ?

I haven't heard of that one I can't think of anything that the programmer itself would use while the truck was not running or the key being turned on. I could possibly see the monitor draining over time if it was powered on but that is ran to a fuse that shuts it off when the key is turned off. I'll have to do some research myself you've got my interest up now.

Mark,

How is your Superchip Flaspaq tuner working out? I'm looking at purchasing a performance chip before we go out west this summer. We have a 2004 Silverado 2500HD 6.0 gasser. Any information would help.

Thanks,
Gary

i ended up getting rid of the bullydog and got an sct tuner with custom tune by eric @ innovative diesel...man, this thing has some serious power .

I have the Edge Evolution programmer for my 05 6L power stroke. It has more power in the tow setting, dose not shift for every hump in the road & hold it speed good now. I like the monitoring , you can see your EGT, EOT ECT & more. You can clear code. Which is handy since I unplug the EGR. You do have to keep a eye on the EGT when pulling long hills. IT dose what I need.

Is this chip set at a low enough output as to not blow your head gaskets?

Get a diesel truck.

Why do you have to watch the EGR? How do you keep your head gaskets intact?
