heinzboy said:I don't know about the Street version, but I have Eric's TTP1 Extreme Race on my Wifes 06. I like it alot. I put the file in with 2500 miles on the odometer and have never had any issues. It will smoke the 35in tires pretty good. The shifting is right on also. This is her daily driving file. It made 371 HP and 765 TQ on Dunbars Dyno. The truck is all stock motor wise.
