well i am getting close to having my intake made for my eaton supercharger. I am going to run with the factory fuel system and use TII injectors and fuel pump. I need to figure out how much fuel pressure to run. What kind of regualtor should I use? I should be running under similar conditions as a factory TII.

 

Planning on running an FMU or electronic fuel management?

 

Personally, I'd leave the fuel pressure stock and control everything with an S-AFC.

 

sounds like a plan with the S-AFC but I have a jet chip ECU upgrade should I go back stock? It bumps the timing up a hair but JET says ti will still support a 75 shot nitrous kit which leads me to think I will be ok with high octane gas. Do I need to geta boost retard system like msd or what

 

Advancing the timing under boost is not a good idea. I'd go back to stock with the ECU.

 

Take it from me,if your going S/C do not run advance timing.I just blew my motor bout 2 months ago after installing the nelson S/C kit.I have 4 550's inj. cartech rising rate regulator and a S-AFC.My best advice is have it tuned before you plan on getting down on it.If not,good luck on rebuild.
