Need a tune for sure.. without it you will get VTC failure codes.Hmm, the 2s might actually be able to run on stock tune, so that might be an option. But looking at the dynos, power falls off fast up top unless you go with the higher lift 3s. That said, could be fuel limitations, or turbo, etc...
Drop at end is cut off at max rpm.
