I had a 99 tahoe that was totaled out about 6 months ago. I pulled my bbp tuned computer off and switched it to my new 99 tahoe. The totaled one had 373 gears and tuned for no cats. The new one has 342 and cats. My mpg on the new one is like 8-9 mpg. Would the diff in gears and such effect this. I figured the tune wouldn't matter much on gearing and things like that.
Weird tuning question
