I drove out to San Antonio yesterday morning because I had a few problems with my edit. I had to get my shifting points fixed, air/fuel ratio fixed, and turn my o2 sensors off. I put about 200 miles on it on the way back home so when I went to work that night I got on it and all I can say is wow. Fixing those few problems helped my truck out a lot. I did a 30 roll and spun the tires, when it hit second the truck went sideways on me. Thanks Allen for another great tune.

 

Glad it worked out for you.

 

What truck and/or mods do you have besides the tune?
