Anyone switch from VF Hex Tune to BM3?

No bucking in stop and go traffic, manageable throttle control in daily driving/track and a much more linear power delivery.

BM3, Alex and Carbahn are the top three IMO.

+1 on Alex at Alpine. Very smooth and linear tune with 2+. Customized a very light burble too.

I will +2 to that for Alex@Alpine. On 2+ as well and incredibly linear and drivable. Car feels like it has a huge ass displacement.

I run cats on mine, can't imagine what it would feel like with DP's.

Terry from BMS has said that stock cats flow very well and you're looking at 30-40hp gain approximately. I chose to keep my stock cats cause compliance in my country is a real bitch and on the MPE, going catless ruins the sound. Real raspy...

Of course going catless, you have more room to run higher boost and better response. Really depends on your setup and your preference. I would have probably gone catless if not for the MPE.
