Default Tuner recommendation? JB4 (methanol) with MHD backend - 07-01-2019, 01:16 PM

Can anyone recommend a tuner for the N54 that works with the JB4 (methanol injection) and MHD backend flashes? The car is currently FBO with methanol, but also looking to upgrade the turbos and get a custom tune for it.

Please elaborate on your experience with your recommended tuners.

So far Ive heard good things about BQ and Wedge.

Trebila is good. He's the only tuner I've ever used though.

If you do the tune and nothing else, it would be very interesting to see Dyno results of the before and after.
