Switched out the 40's to a pair of 44's . Right from the git-go Bench settings Fired up and idled 1200 Rpm. Tweeked em down to 1000 RPM and smooth as glass. I'll mess with them later to get the idle and all the barrels to sync.
Throttle response pinned my head to the head rest, these things pull like a frieght train. WEB cam is 500 lift 290 duration. The 13lb flywheel helps too.
Wait till I put the 205/50's on for AX Sunday.
205/60's for everyday driving.
