Here is what I said and the fix. not sure if your problem but something worth checking:

One thing that is very important that we found out the hardway. Please read the following as it is very important, I would assume for almost any blower install but this was definetly the case with my Whipple. I had taken off work to do this build w/ my friends, the first thing we did per whipples instructions was try to dowload the superchips tune in the car. did not work. Instead of calling whipple then we chose to continue with the job, pretty much had to get cracking as 1 freind took the day off too to help. We got it all done and attempted to install the tune again, called superchips that sat morn and no one was there, spoke to Jeff at Whipple who sent us some HPtuners tunes as we had plans on doing the fine tuning w/ HPtuners since my car is not stock and the superchips tune was for stock. Once the car went into closed loop it would not stay running. We tried everything, nothing worked my tuner came over no dice. Called superchips mon morning they said my Operating system in my computer was not supported by them. I have an early 2010 VIN ends 12,546 and I have never had an update done by GM to my PCM/TCM. My tuner tried and tried to get it to stay running w/ tuning in HPtuners. However, there were tables missing from my PCM that were in other peoples Whipple tunes who sent them to us trying to help me. Thanks again everybody. Well the table that was missing is the Air/Fuel Ratio Analysis program. Its not in the old OS, but is in the new OS from GM. I can`t understand why GM shipped cars w/ out this table. I guess they did a patchwork to get them to run NA, but boy it sure won`t run w/ the blower. Runs fine is open loop, hits closed loop let of on the gas floods out and cuts off no matter what you do. So I took the car to my dealer freind, had to tow it, they flashed it. Starts up runs and drives fine. Disabled AFM and drove it home. Crazy. So the moral here is if you have an older VIN w/ no updates, go weeks in advance and get your car flashed by the dealer w/ the updates. I have been through this pain for you. Don`t make the same mistake....Lol..

I have indeed had the Flash from the dealer. At least they told me they were doing it and I had to wait for a while. I have my dealer do all of my services. So I am definitely up to date. Damn good info though.

Sure did. I got excited reading it but I've had all the dealer updates.

When you get it to your tuner I am sure he will see it trying to make these huge adjustments. Then the problem is to determine the reason why. Hopefully, it is just in the tune itself and he can adjust it so the tests dont attempt to pull as much out..Or maybe just the front 02 sensors turned off or something. You are so patient with all of this...I probably would have been across the county in Tx having Andy checking it out for me by now.
Logistics. This city just doesn't have any shops. Much less good shops. At least none that seem to want to be found.

I hope you get it fixed soon. You know all this pain is gonna be SO worth it when you are done and when you get that win over GTAHVIT!!!
I checked it. I have the single number blade. I was hoping.

Had the flash.

If you bought it after the service bulliten for the air conditioning and I think the heater hose fix then it was done before delivery. It would be very rare to have not already had this done..If I remember this only had an effect on 30000 and under vins but cant be certain on that...sunday morning brain freeze and too lazy to look it up.

Good point to raise though. Once you have a tune installed place tape over your obdII with a warning to the dealer not to flash unless they talk to you.

They will load a flash over the top of your tune and set back to stock and then you wont be going anywhere. In my case I am converted to E85 and the car would not even start on a stock tune and would be dangerously lean.

I am pretty sure PQ has an early VIN.

look at your LTFT and STFT (long and short term fuel trims) and see what they are doing,, this will tell you alot!!

what did you use to extend your map sensor harness to the rear of the supercharger intake, did you use your original map sensor from your intake manifold or was there a map already installed on the supercharger, and is it also reading correct on the scan tool. and is the small vacuum port plugged on the back of the supercharger by the map sensor
All I have is the SCT.

Got codes

P0171 = p1070 fuel trim malfunction, lean condition.

P0300 = P0300 Multiple Cylinder Misfire Detected

P0650 = DTC P0650 set indicates an improper voltage level on the output circuit that controls the malfunction indicator lamp (MIL)

I cna do a data log. But I'd have to send the file to someone who can read it.

no one can fix a fuel injected vehicle with the only thing we know is" there is some smoke, some popping and it dies" ,,lol give us some numbers , some data logs,, whats the map reading at idle, whats the maf reading,, what is the LTFT , ,,,
Above. I just got them. Car still shows no codes thrown. I didnt' look for any becaue there seemed to be none thrown plus I have to get it to a tuner anyway.

I had it tuned before but just a mail tune mainly to get the 02s turned off.
