Tried the Rtek 1.7 chip, but the tuner could not get a safe AFR, so had to revert to a stock ECU and rely on the S-AFC for tuning. Engine runs awesome on the track. It does have an intermittent starting problem and a bit of a rough idle, which I will address during the off season. May try chipping a different ECU.

I have the same setup just with a stock turbo and no S-AFC. What issues did you attribute to the RTEK 1.7 that were fixed with the stock ecu? or was it just you couldn't tune with it?
