I got in my car today to pick something up from my sisters. I take off and get into boost and the gauge starts jumping from 2-9psi (back an forth) and the car started to jerk like someone who can't drive a stick (I was in 2nd gear). I tried going into boost a couple more times but being careful and it would jump a little. I then left my sisters and saw my A/C was on and my windows had been open. I shut the A/C and every time I went into boost on the way home it was smooth again. Was it the A/C being on or maybe the car had to warm up? It was only about a 3mile drive there and 3miles back.

 

I had my AC on one time in the summer and mine kinda acting like this but not to your extreme. I havent turned it on since.

 

This seemed to be the weekend for ODD boost related problems across the board

 

So no real answer to what it could be? I'm putting in my midpipe this weekend and getting it tuned in a couple of weeks. Maybe that will fix the problem.

 

totally agree

 

That's odd. I had my A/C on accidentally and my car was running fine... How's your tune?

 

if i recall....

paul unfortunately is running the basemap from the emanage. titan didnt tune it.

 

The tune is the base map but has been running fine for awhile. I'm gonna turn the A/C on tomorrow and hit boost and see what happens.

 

So I turned the A/C on today and hit about 5psi boost and all seemed fine. I'm gonna hit it a few more times tomorrow.

 

i actually thought i had a skip in my motor but to find out and turning the radio down and lisen to motor.. with the AC on the pumps dose turn on and off while running, you can here it click. when it dose turn on it takes HP from the car . you can feel it while driving. with it off everything is normal..
