I have just had a HKS Adjustable Exhaust cam gear fitted to my R33 Series II GTS-T 96 model.
ITs got a powerfc, full exhaust and split dump, pod filter, 11psi, and 10% mix of toluene.
My mechanic, very respected, (just got 300rwkw out of a VL turbo that day for an example just tuning it) put the cam gear in, and set it to 1,2,3,4 degrees retard, and 2,3,4 degrees advance, and every position the car lost power,
The only position the car made good power was at 0 degrees.
Anyone seen this before? I thought 4 degrees retard was supposed to make more power in the bottom end?
He's tuning the power FC and has managed to push it from 160rwkw to 180 so far, and like 2 hours
He says there is more to go yet
