Sprint Booster + xHP TCU Tune

eDubz · 05-16-2019, 08:48 PM

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?

I agree about the transmission racing to 6th in D. I basically always just shift myself in Sport Manual. Doesn't really bother me to take care of all the gear changes myself.

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

I find just driving around in 9 on the sprint booster is good. I'd be interested to hear how folks like it with the tune too...

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.
