i am wondering what kind of fuel system add on should i use on my 350 tpi twin turbo set up. what can i do to the computer of the car to have it know when to give it more fuel when the boost levels get higher, so it doesnt not get enough fuel and detonate. is there a special prom?
does anyone have a turbo timer

 

do you already have this setup? Really all you would need is a better fuel pump, and bigger injectors, depending on the amount of boost you plan to run. as far asthe computer goes not sure how they tune one of those. the stock computer should have the ability to handle TT, assuming it gets the proper tune. Not sure though.

 

do you thinkthat a 9-1 compression ratio or maybe a little more is good enough or should i drop the compression ratio to 8-5-1

 

As said above injecters and a good pump are all you need maybe not injecters if you are running low boost. 5PSI or lower. You should be good with 9.1. How big are the compressors and how much boost are you planing on running. Tuningand working withthe timingshould also be at the top of your list.
