how much boost can you run with fpr mod and s2 injectors together? the fuel return line is a little expensive and i think its a little much for what i have. i want to spike 23-24 and drop to 19-20. is this safe if i have all that fuel?

 

nobody knows how much you can turn the boost up to?

 

With my little knowledge of turbo cars I would say 20-21psi. I don't about those FPR mods...I'm gonna get a Walbro. I've heard mixed reviews about the FPR mod. Stage 2 injectors are pretty big so you should be able to get the boost you want. You should save $$$ and buy a wideband. My .02
