Hi,I have just got my G6ET back from the Dyno and I have at the moment 369rwkw(You can see the Dyno run on You Tube, Put in 495rwhp Taxi) and I am a bit concerned that you blew your motor with 377rwkw,in the next month or so we where going to add more bolt ons to hopefully get more rwkw, not sure if I want to do this now though, how did the motor blow? Was it not tuned right? Or was it something else? Good luck with the BIG Kw.Cabbie.
