Programmer Help

[bchas92097]

I am looking to add a programmer to my 2008 Hummer H2. I was also wondering if it would help with the sluggish start off in it. It is sluggish under 2500 rpm. I also think that it might help if I can change the tire size also.

I would not be looking for any huge improvements, but I believe it woudl help you some.

You could adjust for tire height
You could adjust shift points/pressures
You could tune for performance which adjust the fuel/air ratios.

Worth a try, they dont cost much anyway.

If your running huge tires, you probably want a regear.

But still the programmer would be needed to get the speedo corrected after modding tires/gears.
