Supercharger Boost..?

Dealer installed 2013 TRD S/C 7-16-13 on my new '13 ....Seems to loose pickup/ acceleration @5200rpms during pull(no speed or rpm limit)....I was hoping the stock fuel pump had enuf pressure to feed the beast,maybe not,,,any ideas besides fuel pressure.....I ordered
a Walbro 255, and Autometer boost gauge just to make sure I don't starve the S/C...? #hmmmmmm

 

I'm trying to find the dyno curve I've seen for our truck with the S/C installed.

The S/C moves our torque and power peak lower in the RPM range than stock. Once it hits around 5k, it starts to back off some as it has peaked.

 

and at that point you realistically only have another 300 rpm to play with, so it should be going for another gear at this point, unless you are A/T in which case there isn't much you can do to force a shift

on edit: if you are A/T (not exactly sure how the ecu programming is, but could it be backing down boost in prep for the shift, so as not to destroy the clutches/bands/etc in the trans?)
