DJ and Viv have been writing me few tunes for my truck I just purchased the SCT frome them over a week ago. Well I have been extremley Impressed with the customer service and the tuner. Well today I tried the Looney Tune at its max......Holy XXXX!!!!! My son got hurt helping me work on one of our 4 wheelers and I had to take him to the ER. He is fine but there for a few minutes I wasn't to sure he got hit in the head with the floor jack handel and cut a gash in his forehead that was extremley deep and blood running down his face. He is 6 but tough as hell. Any way I wasn't worried about getting pulled over so I drove like I stole it.... What in the world have they done to my truck....it is fast as and strong. I was over 100mph and it was still changing gears I didn't think that I was ever going top out. I just wanted to let everyone know that having a tune like this is good not only for having fun but in situations like this u can count on getting there quick.
