I have had a Westers tune and then another live tune. runs pretty good , but I want it to be a real sleeper. Probably not going to keep it too long but in the meantime I want to accelerate hard and pull hard all the way to 100 or so. Heads and cam or should I go supercharger? We have a lot of hills around here so I don"t want spark knock and can only get 91 octane 70% of the time.

Anyone out there has some experience they could share about their set-up on an 8.1? Is the cam the what holds back the 8.1 from making serious torque or does it not breathe good?

Thanks
