Product Questions & Answers

Q:I have a 1998 GMC Sonoma with the 4.3 v6. I was wondering what kind of HP and TRQ gains you are getting? Thanks Show Less
Christopher V.
A:BEST ANSWERHi Christopher, I'm glad to assist you. If you have upgraded your stock exhaust system to a performance type and added a cold air intake, the tuner programmer would help adjust/calibrate the factory settings of your engine's computer to its optimum settings to maximize the added components' performance on your truck. If there is no added component such as a cold air intake or a performance exhaust system, horsepower gains are not possible. You can also call our parts specialist (for real-time live & immediate assistance) on our toll-free number, 1-866-529-0412 (Mon to Sun). Show less
