The cams are small, the turbo is kind of big, the EMS is NOT the best tuning tool on the market, The cyclone is a joke I have one here and will have to test just to make sure, a reliable 450whp DSM is not easy to make happen. Also Greddy use the 25g compressor wheel in the Greddy T78:

I would have used HKS 272/272s at least, but HKS 280s or similar would work better. A stock 1g intake manifold or one of the billion SMIM on the market, A EMS once set up and tuned would be better then a Heltec and you could learn how to make changes, but if the car is tuned right the first time you should not have to change anything besides load a race gas map or something, the turbo I would have looked into FP with all the different BB options etc, a FP 3052 would work good or a 3065. So your user name should be 25g95tisawd, I hope the setup works for you and does what you want/need it to. Also I made 532whp and 500lbft of torque on a FWD dyno guess with a 60trim stock 1g intake manifold and a EMS, running 33psi on C-16.
