Powerloss Help

Well on my way home today something funny started happening.

When I would punch the gas the car would spool and show boost but it was hesitate big time, then after a second or two start moving.

I have a injen cai and a dsm afc.

Is it possible that the afc is malfunctioning or bad connection or even bad gas.

Any ideas would be appreciated my car has some warranty left but I am afraid with my mods Mazda will be quick to blame them.

cracked intercooler piping is what it sounds to me, do this, first check for any obvious cracks... if you cant find them open your hood and have a friend rev your engine, and feel around for any leaks.
