Subbed.Vanos delete plus 296 CAMS which accelerate the RPM much much quicker toward the top end. MPOWER engines loves cams, it loves that extra lift and over lap. I put cams on all my MPOWER engines I have, you will really feel the difference solid power until redline noticeable more than headers and ECU tuning, if no cams then you are missing a lot. Hopefully his summer I will be working on tuning my S85 depends on finding the tuner that I can trust and willing to offer long term support without a rip off. It is easy to install the cams but not easy to get the power out off it and make the engine runs good.
I would love to do this, my car is a weekend toy that seldom sees heavy traffic so I would not mind a much more aggressive top end.
Platii please document and upload your build as it progresses if you don't mind, it would greatly assist.
