Dyno tuned a pretty badass car we built. 99 BMW Z3 coupe, originally M52TU, Swapped with an Iron Block M52. Active Autowerke’s Rotrex Supercharger 13psi, intercooled, meth, m50 manifold, s52 cams, stock motor otherwise. 2 runs are max power on pump and then after turning meth on and retuning with it. Not bad for a 2.8L!
