Hey guys, I'm wondering if someone could give me some direction. I'm having an issue where when the air conditioner is on, the car accelerates. This only happens when I am driving. Whenever the car is idling, you can't even tell that from the rpm's that the air compressor kicked on. I did some driving around and it surges like 1k rpms in first. I basically have every bolt-on except for the throttle body on my car. I've been out of the game just enjoying the car for a while, so forgive me if I'm missing something. Is it the tune or could there be mechanical failure involved? It's been like this since the day he tuned it. My tuner is a local guy who does good work, but he's at a lost on what to do in the tune to fix it. Who's does good tuning for these cars now a days? I have the mtf tune file if someone can help me.

C&L CAI
Brenspeed Detroit Rockers
P&P Heads
Stiffer valve springs
Lockouts
Charge Motion delete plates
Kooks headers
Kooks Highflow Cats
Kooks H-Pipe
New Battery
Pa Performance alternator

 

Sounds like the tune. Did this start happening after the tune and or the CAI?
