So ill start by saying that i have had good luck with my truck thus far. I was racing the other night and it was 29 degrees outside. The truck was running awesome until i got a jerk and it felt like the truck pulled timming. So i let off and slowed down. I was afraid that the weather had made the tune act up a little so i decided to watch my afr closer and see what was up, on a normal day under boost my afr is 11.8ish and when i watched the afr was at 12.1. So i made a little boost and boom, hear a loud pop like a coupler came off at 15psi is what it sounded like. Well i checked under the truck and everything is still good and the truck still runs good but if i get into boost its like it hiccups. other than that the truck runs fine just cant make over 3 or 4lbs of boost or it acts up.

Now the weather is still the same so i havent ruled out the cold weather making it act crazy but my problem is tuning. I have no way to log or send info to Justin and have not been able to reach him.
