Yeah ur right!!! My 515whp z was bogging and running 11.2. What's your excuse for using a 780whp built by Mattz Garage and running 10.8 to 11.0. Due the math. And I don't have to Ask any body, because I know you and what your capable of. If steves car needed a oil change then fine you can do it, other than that your just a liar punk ass biaaatch!!!
