I forgot to add some .02 cents. I didn't go with the throttle body spacer. It reminds me of that tornado thing every body was raving about. Twisting air, comon :lol: it would only work at WOT. Who runs around all day at WOT?:shaking:
i think the programming thing depends on what you want to spend. i think i'd be just happy with the Jet chip.... though i have been looking at the ProComp(?) model that is a power programmer and adjusts (a little) for tires and/or gears.
I added an KN drop in filter with a Gibson exhaust sometime ago. Just added the Jet Chip Stage 1 a couple of weeks ago, I think it helped with the low end power. I have an auto with 3.73 gears with stock 32" tires. Transmission isn't hunting a gear anymore and I am getting 20 MPG on the highway and 18 MPG around town.
A chip that works in Low end power is a good thing. I thought many of those chip company's only enhanced HP and TQ at the upper range due to these vehicles needing to pass emissions which is all tested at the lower RPM range.
