about 3/4 sec 0 to 60 using a GTECH.

Running the 91 hot tune, mileage isnt any worse, and its is supposed to get better after the PCM gets used to the truck.

Id say it was worth every penny, especially since I got a deal on a group purchase!

well the intake was 30 HP and the exhaust was 30 HP and Westers was 30 HP so I now have....

probably 30 more HP total! I think the Westers is the only thing that added HP I coudl feel, though it can pass from 55 to 85 a lot better now.

Anyone have experience with the Hypertech III programmer? My brother has a 5.3 and his buddy went from a gasser to a DMAX, so he gave the programmer to my brother. IS this thing worth installing, any issues to look out for?


Thanks, JP
