Alright i have the stage 1 577cc fuel injectors and im going to be buying a new wastegate here soon. I was looking into getting a electronic boost controller, probably the GReddy profec. I was wondering if anyone out there knows how much boost i could push out safely with those fuel injectors????

 

Dont get the boost controller until you buy the Stage 1 ECU. If you dont then your stock ECU will throw an overboost code. By the stage 1 ECU and Updgrade your wastegate first. Then look into the boost controller. With all that I think you'll be able to boost 17psi efficiently with the 05/stage 1 injectors.

 

well, to begin youll need to get a wideband and mount it somewhere to easily monitor your a/f. and i think 17psi sounds about right for your max boost. while you can push more, youll need to upgrade your injectors and ECU. also keep in mind that the stock turbo has its limitations.

Get a S1 PCM
Need a wideband
Larger injectors would be a plus
