hey guys, I just bought a BA mkII F6 Typhoon off a panel beater, he bought it from auction.. Got the car dirt cheap. Now the car in terms of modifications has a nizpro stage 2 kit on it, plus a xforce 4" dump into twin 2 1/2 exhaust. So I was driving along and the car stalls when the engine is warm.. So I took it to Blue Power racing developments and put it on the dyno for a power run and check AFR etc.. It come out at 298 rwkw at 14psi.. The boost was also not holding at 14 psi to redline, I think was droping down to like 12 or something.. Is this power normal? Guys at blue power said its a "ok" power level considering all the mods? They also said its got a very c##p tune on it, although AFR is ok.. I thought with a plenum at 14 psi these cars make like 340 rwkw, and maybe even more considering its a Manual! One other thing though, the nizpro core was taken out and replaced by a PWR core, still using nizpro end tanks..
