You would probably get more speed out of the car if you took a course at Bondurant or Barber.
Improving the user is far more usefull than pumping out crazy HP.

Much as I love my Klee brothers.....Renn has really worked with Trey over and over to perfect the ECU mod on his SL65. They know him closely as his S600 made them quite a bit of money when he took it to lower 11's with Renntech mods ...it's a no brainer. Renntech and tell them you want Ben Treynor's SL65mod. His is custom tuned for best performance.

They have done all of my Benz and Porsche work (see my sig), I recommend them highly!

Hey Ben, I remember you from Supraforums.com when your Supra was among the most powerful on the site... I remember seeing your car on the dyno with 2 guys sitting in the rear hatch to keep the tires glued. LOL! I see you're still at it! I thought it took crazy money to get the Supras flying but modifying these Mercedes motors takes a small fortune! Good luck with the 65 man...

I went with Kleemann on my C55 and couldn't be happier! The car is a monster and I have had absolutely NO problems with it what-so-ever!
Good luck with whatever choice you make and definitely keep us posted!
