How many people would be interested in a flash tune or even a custom dyno tune from LET Motorsports? They are willing to come to the Phoenix area, and if you're interested in their custom tune, a forum member has been able to secure a dyno dynamics machine at a very reputable shop for the tuning session. If you just need a flash tune, LET will be here so you have zero down time by avoiding having to send in your ECU.

The date is still optional but we need to know how much interest there is.

As per their website, LET currently tunes the following Mercedes vehicles:

C230K, C320, C32, C55, CL55, CL600, CLS55, CLK55, E55, S600, S55, SL55, SLK230K, SLK32, SLK55

Also tunes: Crossfire SRT6, Crossfire NA, Audi A4 1.8T, Audi A6 2.7T, Audi S4 2.7T, BMW 135i, BMW 335i, and BMW 535i.
