It is like sometimes my computer forgets that the car is tuned. I was in comp mode and driving down the highway and it boosted only 18psi. I got to an exit and quickly put it back into comp mode with ESC off and it started going back to 24psi. Could this be related to that map sensor that I blew out a while ago? I get no CEL's and it runs great.

Side note, I just put new exhaust on about a week ago and it has been getting way better gas mileage. It went from 24 to 28.

 

No idea about the tune, but on a side note my gas mileage has gone up a lot. I suspect air temperature and better gas are the culprit.

 

Yea, I think the mileage is the warmer weather and the summer spec Gas. Ive been getting about 27 and I go WOT all the time

 

thats why i have mine activated through the traction control seems to be a little more consistent are you turning the tune on as soon as you start the car or are you doing it while driving
