Rtek 2.1 S4 turbo Lean at primary to secondary stage.
Car: S4 JDM turbo engine, rtek 2.1 625cc/1000cc injectors AEM adjustable FPR. Welbro 255 fuel pump. ECU set at 550cc/720cc. PLX wideband
I am currently having a issue where the car will lean out around 3k, under any condition, near the injector stage point. I was wondering if anybody had any ideas to want may be causing the issue. Vacuum lines routed incorrectly, bad injectors?

It turned out to be the way my Corksport TID, BNR turbo and AFM where setup. The turbo compressor inlet is about 3in where the Corksport was about 2ins. I replaced it with a 45 3in elbow and it runs better. The lean issue seems to be when the car is in the Close loop cruise condition. So I am suspecting that the wiring from my Wideband to the ECU is not right. So it is not getting a correct lean rich 02 signal.
