Looking for Performance chip
Question:
I am now looking for a performance chip for my 95 GMC Sierra pickup. I would like one that works in the complete range, not just full throttle….when the heck are you always at the full throttle setting? Any questions, please ask. Dave
Response:
Not sure if you are in the OBDII years or not, but of all the mods I have done to my ‘89 K1500 (chip, K&N, Flowmaster cat back, Random monolith cat), the only one that really showed any seat-of-the pants improvement was the Hyper Tech Street Chip. It improved towing, mileage, overall performance. The rest made little or no difference. The Flowmaster stuff sounds a little deeper than stock, but is a bit raspy.
