Default Giac X / Revo / Sportec / DBR?

Already STFA but need more recent updated opinions...

on the following setup:

"A box"
Straight Ko4's
AWE Dp's
Borla Catback
Stock fueling
currently Apr v5.0

What mods need to accompany the above mentioned tuners? I am not really a tweaking type of fella! I just want to start and go From some of the experts here.. what is my best option?

ps. anyone else running apr v5 on ko4's.. if "yes" then please give advice on the following symptom.

In any gear, at full throttle the boost spikes to 20-22psi, and then drops to 10 psi, and then holds at 14-17psi. But if i slowly floor the accelerator to redline, I get more linear boost.

It almost feels as if the car runs out of fuel for a split second and then takes off.

btw: what psi are people with similar setups running?

Thanks

Default Revo w/K04's requires 90-95mm maf housing

440c injectors and their big turbo software of course. Giac is a nice alternative too visit www.vastperformance.com very nice page.
