Just installed new TT chip and translator with 3in MAF. Car runs and drives great with the new upgrades. I'am having some trouble with a lean condition / knock at the top of 3rd gear. I have my fuel pressure set to 48psi line off. My knock comes in at at around 4200rpm in 3rd and increases from there iam seeing 5.7deg at 12psi of boost. I can also hear it. My O2 volts seem to drop as knock increases. .662mV is what iam seeing at 5.7 deg. Eric had the WOT fueling set to +10.9% and I bumped it to +14.1% and that made a slight difference. I would hope that my injectors aren't maxed at that low of boost. Another thing I would like to know is what are you guys seeing for airflow at lower boost levels. I seeing around 145-155g/s through the whole range at 12psi. Should I be pegging the MAF reading a 255g/s at that boost level? Another thing iam going to do is try a differnet gas station to see if it might be my gas but I doubt it. Let me know what you guys think and give me some ideas.
Thanks, Dave
