4znova1 Posted March 30, 2007 Share Posted March 30, 2007 About how much boost can be run using the stock turbo ECU, stock turbo injectors with increased fuel pressure? of course using an intercooler and free flowing 3ich exhaust Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted March 30, 2007 Share Posted March 30, 2007 I know you hate searching... but 10psi without an intercooler 12-13psi with an intercooler. sure you can run 15psi if everything runs smoothly.. have an AFR guage or detonation detector?! I would recommend using one unless you like rebuilding your engine.. since you have a metal head gasket your pistons skirts or rings will blow first. By the way what is your FMU (RRFPR) ratio?! 1:1? 1:2? it will make a difference on fuel pressure. Quote Link to comment Share on other sites More sharing options...

BTW, if it's 1:1, it's not a rising rate regulator, it's just pressure referenced. The stock fpr will do that. Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted March 30, 2007 Share Posted March 30, 2007 I was quizin the guy But I agree.. 1:1 is the stock fpr ratio. =) Quote Link to comment Share on other sites More sharing options...
