Recommendations for MSS54 to MSS54HP conversion

[Casa de Mesa]

Hassan/HTE will do the physical DME conversion?

If I had to do it again, I'd probably go HTE since he ended up remote dyno tuning my M3 as well.

I see Kassel offers this service but I've heard mixed things/feelings so I want to see who people on the forum have been using? For my case, I'd be doing the conversion to run the karbonious airbox w/out the flap, and with stock M3 cams.
