Bad MAP sensor?

[NickW3]

I finally found out everything to get this car running good after getting this tune ~8 months ago. Got 2.0 coil packs and raised the gaps on the plugs some about 2 weeks ago, and it runs good now. Runs smooth at all throttle positions, WOT it runs the proper 22psi of boost, vacuum is all good, have the proper bkr7e plugs, etc. etc. what I'm supposed to have for this tune. I went somewhere today and ran great going there, when I get there and am waiting around with the car idling, I turned on the A/C cause it started getting hot, and when I'm about to leave and turned the A/C off the car started running like shit. It feels like how it first ran when i got the car tuned and forgot to put the MAP sensor in. Bucks and stutters and spits and just runs nasty. Spiking idle and rpm while driving and spiking boost, the usual symptoms of not having/bad MAP. Looked at the plugs and they're black, and the cylinders themselves reek of fuel; obviously running rich. Making me think even more it's a bad MAP. Cleaned the IAT sensor and that changed nothing. It all points to a bad MAP as far as I know, but I don't want to buy a new one if I don't need one. So I'm seeing if anybody has any other ideas on what might be wrong. This is my daily and I need it to run well enough for me to get places, so I need an answer ASAP lol. Thanks for any replies!

So it happened as soon as you turned the A/C on? Could something on your A/C control system let go and caused a vacuum leak? I'm brand new to owning an Audi, so I don't even know how it works, but in many cars it's vacuum actuated. Check your MAF plug is clean, still plugged in. Other than that - do you have a CEL on? Wish I could be of more help.

I always noticed my AC draws a lot of power when turning it on, like an unusual amount power; and when it kicks in to keep the temp at the correct setting. The AC isnt vacuum controlled though, and this for sure isnt a vacuum leak. It acts no way like a vac leak and my boost gauge reads fine. MAF is fine too, i unplugged it to see if it changes and it runs worse so i know thats working. No CEL and I don't have VAGCOM (like i should) so i can't check codes. Went somewhere else tonight after fucking around with things to try to fix it, and it ran bad for about a mile and now its back to normal all by itself It makes no sense lol. Thanks for the reply!
