Also, this is the only mod I can really do that keeps the car looking and feeling completely stock. It's not that I just want to keep the warranty, I'm also leasing to buy so I need to ensure everything I do is either easy to reverse for the inspection or looks stock (hence buying the GM intake instead of another one).

302blue Nicely done. I stand corrected. If you have a lean bank code the ECU is make a 25% change in fueling and the still get a lean indication. The airflow change with the CAI is on the order 3 or 4%. The GM CAI must do bad things to the MAF air flow. I bet they designed the intake and as soon as they tested it found they had a problem. As alway GM said "we can fix this with a cal change". Makes senses to now why they need the cal change to the MAF table.

Interesting, though, the one I will install has been installed on my crashed and totaled Camaro SS 1le. So, will GM give me the tune at all when it's installed on my new car???

After Tune/Calibration Update
Actual/Proven Differences:
Using the BlueDriver scanner I actually recorded the live readings on the way up to the dealership (without the calibration done) and on the way back from the dealership (with the calibration done). Obviously, the engine code goes away and the car runs normally again. Below are the links to the recordings. To summarize, you can see before the tune the car is compromising for running lean by providing up to a 40% fuel trim. Afterwards, that drops down to around 10%. For reference, you want that as close to 0% as possible (Negative % means the car is running rich and it is cutting fuel to compromise). From what I found online, most cars are -/+ 5-10% with older cars going up to around -/+ 15%. 10% may be on the high side of normal, but that is still 1/4 of what it was beforehand. Opinion/YMMV Differences: Before the programming I mentioned that there was more of an initial hit/sensitivity in the throttle. My experience was that it eventually developed two other weird effects. The first one was that the car naturally wasn't running very well. Getting it moving (since it's manual) became annoying and taking it above ~4500rpms there was a significant loss of power/acceleration. The other effect was that it would hold revs and engine braking became basically useless. This is really obvious as whenever I threw it in neutral to come to a stop it would only drop down to 1600-1800rpms until I was completely stopped, then it would drop down to the normal engine idle speed. After the programming, all those issues disappeared. No more jumpy throttle or weird engine crap. Unfortunately on the way home, as others have said on here, I barely noticed any difference. Mostly, it's just that it pulls a little bit harder in each gear. Maybe on a drag strip it would easier to see/prove, but on the street I really don't notice any life-changing difference. Not saying that's necessarily disappointing or a bad thing. At the end of the day that's almost exactly as I expected and it's nice to have it for more aesthetic/maintenance reasons. |

GM says 15% reduction in flow restriction with the GMPP intake. Seems to me this would only really matter at WOT and high RPM. I would love to see a before and after dyno of bone stock and GMPP intake with tune. Seems like there should be a few extra HP in the 5-7k rpm range given the lower restriction. I do know it sounds good with the intake!
