yeah mine (t04z 0.84) seems to fit what i need very well... mostly street, soon to be a little drag and circuit
considering the build of my engine, no head porting, stock plenum, valves and throttle bodies getting over 20psi boost at about 3800rpm in 4th gear and looking like it will make 450rwkw fairly easily you cant go wrong.
still when people using t88's seem to be making just over 500rwkw compared with nearly 470rwkw from a z but with more than 1500rpm more lag, it seems a bit pointless to me to go "the big single"
