don't know if this is gonna help you at all , but my injectors are scaled @ 4820.of course this my not work @ all for your car.it takes awhile to get the scaling dailed in.just try to get the A/F correction & A/F learned as close to +/- 5% as possible.it doesn't have to be exact,just a close as possible.for example if your A/F correct. is -4% & your A/F learned is +3% it falls withnin the +/-5% range.also your gonna need to reset the ECU a few times to get the A/F learned back to 0.BTW do you have an intake on the car? if so put the stock air box back on.get the injectors scaled than you can tune for the intake.
