Review on Jet Chips 294055 Computer Chip by Josh Elkins

Fast shipping as it was a replacement for an incorrect part number listed on the Amazon app. Your best bet is to call the company directly to provide the original Prom part number and they will tell you which part number to obtain. After a simple installation, the truck works great. Noticeable pickup when accelerating and runs smoother throughout. It's level 1 with 89 octane. Haven't tried pulling it yet. Set it up on a 1994 Silverado 350 5.7 TBI with a new engine in a box and transmission, with headers and a 2" TBI spacer and a professional grade air cleaner. Nice improvement for the price.
