Default 98 Z28 tuning problems

Ok I have finally got to the motor after suspension and driveline improvements. So I just wanted a cam only car. So in goes pro products 96mm intake, throttlebody, and fuel rails, walbro 255 pump, Bosch 30 lb injectors(36 lb@58psi), MSD BlasterCoils, and Tick Polluter Cam. Everything going good til tuning process. Car hesitates (damn near dies) from 2k-26 rpms then at 27ish BAM! Full power like I'm trying to launch at the track. Apparently a 98s pcm is untunable with what I gave put into the car? Can someone verify this for me? Because the only options they have given me are 1) get 00-02 pcm and re-pin it for my 98 harness or 2) get 00-02 pcm with wiring harness and install it all? As for now car is parked and that isn't cool. Any ideas please!?

You've got something else going on, 98's can be tuned just fine. I make 500rwhp with a nasty cam on a 98 pcm.
