i know this thread is a little old, but...

I'm having the same codes (29E0/29E1) with the DP fix. I'm FBO, kittyless, stage 0, & map 0 for emissions. I'm on 91 octane but I was running E40-E50 before no codes with BMS flash.

I tried 5, 6, & 7 o'clock positions on the DP fix. Resetting lambda each time and doing a drive cycle for OBDII readiness. Never got the 2C31/2C32 or 29F4/29F5 codes. Only 29E0/29E1 each time, but no dash lights.

Since I didn't have a dash light I gambled and took it in for state inspection, It passed. My state does the OBDII inspection only.

Just an FYI...

@robbek reply?

OP. Awesome, I like you, Push them to the limits and have a good time.

Tony, Good man, lol.

Just push the $#@! out of them if you want. If they break, just call me and we will handle it. $#@! Dzenno put 28-29 psi to the stage 1's and was pushing 21 psi to redline just to see (something an RB wont even do). Turbos were pulled off the car working fine and are in route back to me for inspection. So far they seem very durable. Batch 2 is about to stir things up.....
