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.
Are you running the stock TMIC? Just curious, as it looks like your setup will be similar to mine in many regards once I get to the performance stuff after I finish the paint and body.
