and a tune.
326/312 at the rear wheels.
Obviously the exhaust is hurting these numbers quite a bit. Any thoughts? The first dyno pull netted 277/271 at the wheels after a base tune.
FOREWARN, I didn't go in expecting a ton of horsepower with a cam only. I know there are a thousand other things that assist the cam and the other way around. Basically, I'm just looking for thoughts or helpful input. Thanks.
And to those who say it's stupid to start with camming a car...well...I have a cammed GTO and you don't
