    Regal stage 3.5 + inlet cam

    i've jsut fitted the regal inlet cam today, and plan to upgrade to stage 3.5 soon, but does anybody run the stage 3.5 setup plus have the tailored map for the inlet cam? also has anyone got any experience with the tailored software for the cam and does it smooth out the idle, etc.

    Apparantly it will smooth out the idle - yours a bit lumpy I'd presume after fitting and running a std map?

    yeah at idle you can feel the uneven-ness of the engine. ive had fast road cams before in other cars, but this is alot more noticable. i also measured the cam lift of this regal cam with a vernier gauge, and its jsut shy of 11mm lift, which is pretty extreme compared to the standard 9.5mm lift on standard camshaft. not been tempted to take it to the limiter jsut incase the fuelling isnt there to match improved breathing.
