well this is my first turbo car....and it has been great so far....the weather is changing and today was hot as hell and i had to drive my car a lot today....car was idling pretty rough and shut off twice on me.....it seems like the car is idling lower that it normally would.......that car is pulling a bit less vacumn as the boost gague reads....normally it reads vac to 10".....now its vac to 5" and i have a greddy profec b spec II and it usually reads -99 at idle sitting still now its at -78/-85 during the day when its hot....i think that i need the car retuned to fix the idle and also the a/f because the car is running up to 12.5 at WOT on 10lbs.....

any input would be greatly appreciated....just seems like the car is running a bit sluggish, and i know all of my n/a car ran a big rougher when the summer came around, just want to know if its worse when its extremely hot.

thanks in advance......
