Hey guys, I've got an st170 and am considering chucking a bit of money at the motor, I realise that being 160bhp ish out of the box, real gains won't come cheap, I've read about adjusting verniers on stock cams, using different intake ducts etc..... But was wondering if the standard management could be re-calibrated to work with a lairier set of cams, catcams list a few sets, but with the vvt, what options do I have? Has anyone done much research into tuning these without going FI???
