replied to the thread Before and after dynograph showing the difference between a custom and canned tune - Brentuning dyno tuned W211 E55 AMG M113K
" WOW!, I recently posted a thread on another forum inquiring about the same thing "custom VS canned tune, WHICH IS BEST?", it never got nearly as much traction or data behind it as it did here, but WOW!, I'm glad I came here, I had recently exchanged emails with Jerry/EC and I had a long phone call with Jeremy/OE about custom tuning for my M113k, both have been great to deal with, but I have to say, getting Jeremy/OE on the phone for an hour discussing the benefits of a custom tune was priceless, I also exchanged emails with Jerry about doing remote custom tuning, still deciding which will be the best route, in my case, and after reading ENRG's post, I'm definitively leaning towards OE's personalized service.
With that said, EC has done my TCU and gave a tune for my CLS, they run a good business down there and based on my experience, I would recommend them in a heartbeat.
Bottomline, custom tune will ALWAYS be better for your car, but until seeing that graph, I didn't realize just HOW MUCH OF A DIFFERENCE it makes!, specially if you are running massive mods. "
