well i have already had my car on the dyno, and it seamed ok SAFC II, the R&R does not actually mean you have reached the limit of the airflow meter.
It means you have too much air flow at a given RPM.
How does R&R feel, mine just seams to stop pulling and then takes off again.
ALSO, i have all the supporting mods, pump ect, so the car is good but the ecu sux, i am going to try and buy one that has the R&R removed and go from there.
However my coild are shit and i had to regap down again on the weekend, it seams everymonth they get worse, so down to .7mm we go
