ANyone with HPTuners near Philly?

Having an idle dipping problem, and LS1edit didn't help any to fix the issue. This is post TR224 cam swap. Idle dips when slowing to a complete stop or when disengaging the gear.

I don't think this is a tool problem, it's an attention
to detail problem. There is weirdness in the throttle
cracker tables which jerks the airflow desired value
around right before landing onto idle, and any idle
tune / low-RPM airflow tune errors from the cam
will make the PCM struggle to find its feet every
time it steps into idle.

Maybe the LS1Edit just needs a better driver, or
said driver needs more coffee.

Guy who used edit tried a shitload of tunes to no avail...I was hoping a more up to date program would help out. I know the HPTuner allows you to log the data which makes life easier. This dip is f$%king annoying is all I know.
