Question Log review: PWG, Pure Stg2 - trim spike and boost drop? - 11-20-2016, 05:16 AM

Hi

Got the Stg2 dailed in pretty good but I have one question:

This jump in trims @ 5700rpm together with a spike in AFR and drop in boost - what can I make of that?

Ideas how to pressure test with 25psi? I am pretty sure the Pure high flow inlet will shoot out or the plastic inlet pipe will burst at those pressure?

Trims spike because DME BT drops there. On boost dropping since PWM is high its either leaking somewhere or just unable to keep up the required massflow.

What is causing this drop in DME boost target? Boosting too close to target? From my experience DME boost drop is usually associated with throttle closure but not here.

Were you ever able to hold more boost then that up top? Stage 1 turbos don't flow much up top
