Tunes add refinement and give you some options like a higher redline or a coldstart delete or a rear 02 readiness fix for catless operation, but don't add dramatic power. Typically, they add upper rpm power, in the range of 10 rwhp.

The only exception seems to be the meth tune that allows timing to be increased at lower rpm. It adds power across the rpm range and more than a non-meth tune. I think it has the potential to add 20 rwhp. The downside is that it costs twice as much as a non-meth tune.

I went from 363 ( with a tune and magnaflow exhast ) to 402 with proceed, meth and magnaflow exhaust. My math is not right but thats more than 20whp.
