Grand Cherokee SRT8 (2007)

[BJB]

I have a 2007 G.C SRT8 with the following modifications:
ASM (Arizona Speed and Marine) Supercharger system (5psi boost) with intercooler. Larger injectors and different spark plugs.
Unichip engine system (to deal with the boost)
Kooks Headers w/ catless midpipes
B&B Catback exhaust system
2wd switch, ESP switch and fan switch (Driver controlled)
Dashhawk engine monitoring system
The problem I am having is the vehicle has a huge hesitation on WOT shifts. Chrysler knows about the problem yet won't help due to the modifications. Off the record I was told "If the engine revs too fast, the transmission can't execute a shift before it hits the rev limiter. The transmission computer would need to be recalcitrated to start the shift process sooner." Can a custom tuner correct this using the U7135 programmer? What about the added boost, custom tune? Comments please.

So far feedback on the shift settings has been great.
I would imagine a custom tune and some shift improvement would wake that thing up big time.

Thanks
