I want to make my 92 GMC Sonoma Gt with a CPI fueled 4.3 Vortec into a TPI system. Seen a lot of things people have written about the system and it's not looking good. Plus I want a few more ponies and miles out of each gallon. Not looking for a hot rod in this one. Going from a Suburban to an S-15 has made me nervous. Not enough ass on the truck to make it feel stuck to the ground like my big truck.
