Do you not have a tuner? Just an exhaust?? How can you expect a 7-8K truck, with no real performance mods, to beat a lightweight car that's designed to be raced? Order an SCT tuner with extreme tunes from Innovative Diesel. Talk about power!! Plug it in, set to race, hit the gas and hold on for dear life! What a rush!!
Don't feel too bad for losing, those little rice burners are built to do that. You just gotta add some perfromance mods and you'll totally smoke it next time.
