Drives great! Have not been to the track..but, I did race a 2016 GT, with an exhaust and intake...he was no match from both a dig and roll. Of course, said race took place in Mexico and on a closed course. (ahem)
I am running the KB tune, and I bought the "switch chip" which, I think, is all you would need. This is why: Am I to expect that KB does not know how to tune their kits for maximum *safe* power, after having designed the kits themselves?
According to KB, adding race gas, flipping the switch, and I get 20 more rwhp. No pulley changes, safe on my stock block. Then, when done, just flip the switch back...fill it with 91 octane..and enjoy my A/C and stereo!
