That's a good strategy. In bracket racing you will see lots of 11 second cars running in the 12's. In SuperPro you will see lot's of 8 sec cars running in the 10's. It's all about not pushing the engine to it's limits. I understand why the do it, but they are just call sandbaggers. It's ok to do though, makes you understand your launches even more. For just test n' tune days, then it's no fun.
