Not bad those numbers are pretty much on par, but as stated the T-5 or T-45 swap won't help out much. The 4R70W transmission sucks between 20-25% of the hp out the car. The T-5 and T-45s suck right around 16% hp. So you'll gain maybe another 10 rwp over your current runs.

What about when the hp numbers get higher? 25% and 16% will more than a 10hp difference right?
