Not to be that guy, but your slk55 dyno shows 261whp stock and 280whp tune only?
Really? 362hp to 261whp? 28% drivetrain loss...
This is not relevant, the importance is the Delta of 19whp gains. Our OLD dyno dynamics that we do not have anymore read very low numbers like a Mustang Dyno. The weather correction factor also may have been inputed incorrectly and since we are in Houston Texas it may not have factored in the 100 degree summer at that time. The point is, a tune will gain you about 20whp in the end on a NA SLK55.

Thanks
It's my basic understanding of numbers that since it was reading so low, the gains would be even better had it been showing less of a loss. An ~ 7% gain @ 261whp comes to the advertised 19whp gained. Say that starting number was closer to 300whp, which isn't a stretch, that comes to a 21-22whp gain. Not much, but if anything, the website is being conservative, which I much prefer over most BS strewn about by most "tuners" these days.
Regardless, $250+tax for about 20whp and even more torque (hp is great, but it's the torque that really moves these things). Yep, I'm already on board.
