I even get my posts deleted from this forum if I don't watch what I type out.

I just had 2 F10 M5's flashed by them recently and sending out a F06 M6 ECU's to them in the coming week.
Their tunes are the real deal.
There are multiple shops in CA that have GSR tuned vehicles.

It would be good with before and after Dyno.

What type of dyno, mods, etc are all factors as everyone knows.
I have a graph that I can post up.

I will be dyno testing a F10 M5 with catless downpipes with Eisenmann exhaust next week.
Stock and modified GSR tune.
I will post up that information.
