works on 99-05 gm/chevy truck/suv
with 4.3/4.8/5.3/6.0/8.1L Vortec Engines


anyways, i tried this in my truck for a while, my friend owns a car shop, and he custom tunes now with EFI-LIve, so... one customer had this as "trade in credit"

my buddy let me borrow it to see if i'd like it - but i cant afford it, and he is going to put it up for sale at his shop soon, but i figured i'd offer it up here incase anyone was interested

$150 - shipped

slight mileage gain, more power, mostly you'll notice the shift firmness - i'm going custom tune sometime because i seen the difference this made on my 2500 8.1L avalanche
