so i just put a 350 tbi in my car and i still want more power, so i have decided i will switch to tpi in the next year when i get the money to buy a setup. so my questions are what type of injectors can i use? computer? fuel pump? wiring harness? also is there any free tricks to get more power out of the tpi setup? i know there are budget tbi tricks but are there any for tpi?

 

no one can help me out?

 

well you need a wiring harness. you can get one through summitracing.com . The Tpi intake- you can get that over craigs list or ebay CHEAP. need a few 20 dollar sensors. a computer with custom chip.Theres two systems of TPI. SPeed Density and Mass Air flow. I would make it a MAss air flow system better response. tons of power adding "free techniques" can be done with tpi. eight 24# injectors with a high output pump. But Mainly first id get a Intake manifold and plenum first. then harness/computer then sensors then extra needed stuff. my opinion only. I got TPI with 19# injector rated 10% more richer fuel 5.0L also Mass air flow.

 

what years had the speed density and what years had MAF?
