Im looking to get feedback on what would be a better route for a tune. The Alpha 7 tune is about 3k while the renntech tune is about 3495 while the cheaper of the two is producing ~40hp more. Renntech has been doing Benz tuning for years whereas AMS is fairly new (to the best of my knowledge) to Benz but has been a proven tuner for the Nissan GTR's.

I opted for Renntech..no regrets..I'm certain Alpha would be great too..

Awesome ride! If I may ask, how much more hp/tq were you able to generate from the tune?

I believe it is currently sitting at 669 hp up from 550 hp and 738 up from 560 ft lbs...an impressive increase

This performance at 2500 fasl

I also have been looking into a flash. I've decided that I may just try and save up and go for the Alpha 9 package. I've seen what they can do to a GTR and I've also seen their Alpha 9 E63 which hits 10's in a quarter mile.
