I am new to working with fuel injection and am trying to figure out if a stock TPI system will do what I want or if I should look at an aftermarket setup. I am looking at building an engine for my Nova that will be a 383 with Vortec or Etec heads. I know Scoggin-Dickey makes a Vortec TPI base manifold. But I am not real sure how adjustable the TPI systems are and how it is done. 1. Would it support this type of engine combination? 2. Am I looking at hooking up a laptop to reprogram the computer or will I have to look at burning chips. Any suggestions and/or links to help me understand these systems would be appreciated.
