Powerdyne Questions??

I am looking at buying the Powerdyne 9psi kit. The guy that does a lot of my work says that the last powerdyne kit he installed worked great with the FMU. I have heard horror stories though. I have stock 19lbs injectors but a C&L mass air. Stock throttle body. It has an E-cam, GT-40P irons, and a trick flow street heat intake. Any suggestions for parts before i jump into the charger. I would like to have the car dyno tuned as well so take that into account. Thanks....

tuning will far easier if you can avoid using the FMU, but the cost of tuning without one may go up because of having to buy new inj. and most tuners I talked to try to avoid C&L MAF's.
