You sure about those numbers Harald? On my IPD cam, 1mm open required around 1* advanced. Taking into account the head height, I'm running 4* advanced, for an actual of 1* against the crank.

Yeah, it's not as torquey off the line as my VX was, and it doesn't bark on the 1-2 shift like the VX, but it also winds out a lot better, pulls better across the band, and doesn't hit a wall at 5k like the VX did.

OP, assuming LH2.2 car here, since you're talking advancing the timing. 12* should be fine, definitely check cam timing, make sure something didn't slip a tooth.
