Rev-up cam timing?
Rev-up cam timing?
The more i hear my car running the more i question using normal DE timing with these cams. Once its above 4500rpm the car really comes alive. but anything under that, at first i thought it was just the SSIM. But im not too sure listening to the car more and more.
When im driving around normally like around 3000rpm it sounds as if its misfiring. Plugs are all nice and dry. Since the motor is getting ready to come out(annoying O-ring oil leak) i can change timing. Torque is there It has quite a bit more than my stock AT, i just feel i could be a lot stronger.
Specs of cams:

Any ideas?
