Remove the 19lb injectors :shrug:

Yeah... Not sure why that problem is so common here. The summary is: your computer is calibrated for the 16 lbs injectors, and you have 19's in there. As a result, you are running *really* rich. I understand the Pro Flow MAFs are not calibrated to anything below 19's... unfortunately, your PCM is calibrated to 16's.

Net effect: Pro-Flow MAF is incompatible with stock computer if it has no piggyback etc.

Possible solutions I can think of:
-Upgrade to SVT computer (not recommended without SVT cams, I believe)
-Swap back to your stock injectors
-Get a chip from somewhere
-Think about running the stock MAF

The key here is that you have nitrous. You have a wet kit, so you have an additional "injector" for lack of a better term (the wet nozzle). This extra injector will provide the extra fuel the car would need during a nitrous run, so my recommendatation would be to pull the 19# injectors and MAF and go back to the stock 17#ers and the stock MAF. You will have to tune the vehicle either with an S-AFC or other piggyback computer to make sure the wet nozzle is providing enough fuel to compensate for the nitrous.

I would also recommend running this by the folks on the F/I forum, but I believe they would back me up. The problem lies in the MAF/ECU injector calibration. If you can get a MAF piggyback or a re-calibration, you may be good, but in my opinion, an aftermarket MAF is unneccessary with a wet system.

Get rid of the MAF...

Echo?

Let's make it 3.

Definitely ditch the 19's until you get a chip to tell the PCM you are running 19's.


The MAF I would keep unless you still have problems after you switch injectors back and the PCM relearns again.

Hay all i figured out the problem lol it was stupid we missed one of the hoses under the Tb that was causeong my vac leak and thus the idel issues so thats fixed now and the car runs well so all i need now is the svt uim and tb to reduce the richness of the mixture if thier even is any at all ( prolly is but no biggy will get that sorted out soon )
