I did the paypal deposit, got the programmer in a couple days, did the software load, returned the unit and have my money back already. Saw an immediate increase in throttle response and have since driven my 200 miles. I'm pretty much good to go. Thanks!

Ditto for me, except I only have 50 or so miles on mine since the tune.

03 clk500, 06 qx56
can anyone explain how come it takes a while for the tuning to kick in? i reprogrammed the ecu in the qx56 and right away i can feel the difference...

ECU needs to adapt to new settings, i drive my car aggressive all the time so it was hard to notice anything, but when tested against stock the outcome was obvious.

Of course- It makes your A/C feel better when you use the foot setting and makes the rear seats more comfy over 63mph!
Seriously curious, what other benefits would you ask out of an ECU tune than performance in a perfect world?

Got my tune today. Easy. Just need a laptop connected to internet by wifi. Took about 30 minutes. Not sure how much of a difference yet, but I can say that sprint booster and air intake helped a lot as well. It is a transformed car. After this, not sure what I would need a clk550 or clk55 for - it is very responsive and plenty fast.
