Just been to dyno my car. The current list of mods is US Spec 3ltr M3 cams, Big bore Throttle Body, Decat, M3 Backbox and a fart valve. On an M50B25
And the dyno shown 172.8 HP The fuel map shown that the car is running wayyyyyy too lean! And it is very very lumpy. Has a massive dip at about 4.8k revs and the max torque is 166 ft/lb.
Rather pittyfull to be honest. Altho the peak was at 6080 rpm
Any suggestions? But the AFR is rediculas. It goes up to 15.2 at 2500rpm and then drops all the way to 13
Will upload the pics of the graphs a bit later.
