Unhappy where to shift???

alright i have a new s4 rebuild with s5 rotors, a gasket matched lower intake(base manifold), removed 5/6 port sleeves, RB header with strait through 2.5in exhaust, tb mod, cold air intake, 550cc secondaries, all smog stuff removed, removed ac and ps, all cats removed and i think that might be it.. i am figureing around 175hp at the wheels bc the stock numbers were 145hp at the wheels so i think my mods would take to around 175hp.. does this sound right?? i just dont know where to shift for peak power and porformance. all the help appreiciated

well i shift my 91 at 6.5k-7k when i race. i dont like to redline to much. but if you are talking about chirping tires shift around 5k but if you are racing take it to 8k i shift lower cause i have low compression and i dont want to risk anything
