    Default 92 Vortec Fuel Injection Change Over

    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.

    I've never seen a TPI system for a 4.3, do you mean a TBI system?

    No, I mean Tuned Port. But if they don't make'em, I can't use'em now can I. What would be the best replacement for the CPI system on my 4.3?
