Sprint Booster + xHP TCU Tune
My biggest complaint with the M has been the power delivery...the transmission always wants to race to 6th gear when in D.
I started with a Velos tune which helped...then I installed a Sprint Booster today and it has made a HUGE improvement! The M feels awesome...the transmission is the only thing holding it back (manual please?!) I'm wondering if anyone has tried the xHP transmission tune with a Sprint Booster?

Not saying I wouldn't consider a transmission tune though if it really makes that big a difference.

Stage 3 xHP wants to hold every gear until 3k RPM. I don't think the sprint booster is needed for my driving style. I prefer being able to back off the pedal a bit and get that upshift.
That said... the tranny flash isn't a game changer for me, but peripherally it's nice. Definitely consider it to be way overpriced. |
