Another recent post linked to a concern about transmission damage caused by stages 2 and 3 xHP tune:

I'm wondering if stage 1 does much to fix the sluggishness of the transmission (I'm not shooting for blistering 0-60 or quarter mile times) or if another transmission flash program would be safer for the car while still offering increased performance (Alpina B3, perhaps, if it's still available and can be installed by the end user?). If xHP stage 1 effectively eliminates the lag without crazy high RPM shifts, I'd be happy to run it most of the time and perhaps just uncork stage 2 or 3 for a grin now and again.
I'm also wondering, would a pedal tuner be a safer way to get rid of acceleration lag without putting the tranny at risk? To improve responsiveness both off the line and when shifting during spirited driving? ...or maybe a "safe" tune (xHP stage 1?) PLUS a pedal tuner?
