Hypertech 120121 Street Runner Power Chip for 1990 C15/25 350 TBI Auto W/OD Reviews
 Nice!!, By Brian K Bogacz (COUNCIL BLUFFS, IA, US) - See all my reviews Amazon Verified Purchase This review is from: Hypertech 120121 Street Runner Power Chip for 1990 C15/25 350 TBI Auto W/OD (Automotive) Gives that old truck some extra power and better sound, maybe a little extra mileage as well but shoul since you need to buy premium fuel or octane boosters at the very least. Overall would buy again, good product, easy to install!! |
