Well you might have to do the idle learn procedure again. You will need data-loggit or something like it so you can save your tune and load back into the PFC after you do the idle learn procedure.
What you would have to do is initialize the PFC meaning you WILL LOSE ALL SAVED TUNES! So thats why you need a dataloggit to reload your tune.
First you initialize the pfc. Then you input your injector corrections. Next, turn the PFC boost controller to off if you are not using it.
Start the car and let just idle for 10 minutes. After the first 10 minutes turn the deforster on to simulate load and let it idle for another 10 minutes.
Then turn the AC on if you have if not just turn your headlights on and let it idle for another 10 minutes.
So all in all you should have let it idle for 30 minutes. After 30 mintues if your idle is still hunting play with the idle screw on the IACV untill it stabilizes.
Then load your tune from the dataloggit and bingo.
