So far I am the only Weistec tune and I am located pretty far away from most of you guys.....Macau!
I have Weistec ECU, downpipe, high flow filter, VTA and large transmission oil pan. It's been a year since my tune so far zero issue and pretty satisfy.

If you're not trying to be the fastest and you just want a good daily that's fast enough, then sure, buy one. A tune only will add about 80hp.

eh not really chasing numbers.
right now my m5 has 610wheel, quick, but nothing crazy.

I think Guilty is commenting on the fact that the BMW aftermarket is significantly more mature and widespread than MB's. This gives a lot more options for go-fast parts for the M3/M4 than for AMGs.
Potential-wise, the M17x motor is just barely being tapped right now and can likely exceed the N/S BMW series motors.

Benz has always been behind in the aftermarket game vs BMW from a tuning and mod perspective to even aesthetics. As soon as the F8X M's were coming out, there was carbon fiber everywhere LOL.

Picked up the OE tune several weeks ago and plan to get on a dyno when time permits. I'll report back the numbers when I get'em. The car has been transformed and I'm happy with it so far. The car is even unbelievable in comfort mode. For comparison, I had Rebellion prior to OE and the ECU tune feels the real deal across the board. Having said that, only the dyno stats can quantify this to some extent.
