[QUOTE="Daniel, post: 194761, member: 1260"] Good Point, but the issues which i have now are actually when i rev it past 4000rpm. From that rev point onwards, it all goes pear-shaped. My AFR meter indicates LEAN and the car surges. Its knocking too. So no more WOT runs. But if i gently rev it up, no issues at all. Was considering reseting the ECU by removing the batt for 15mins......but is that going to reset the ECU's recalibrated fuel map? Guess this happens when we try shortcuts. So no more. Gonna get a F-Con installed after CNY and go from there. [/QUOTE]
