That stage six gets less horseepower and torque than my CLS...is that possible?

Because, based on your logic, all I have to do is find one data point that is opposite to yours and I have disproved your argument. Simple as that. Give us a credible explanation and all this data discussion becomes moot. How about it?

Thanks for the pic Adam. I stopped by Dyno Comp earlier in the week and got to see this SL55 in person. The new intake and air box were not installed but the intercoolers were most impressive. I was very impressed with Richard and the shop and plan on having him work some magic with my CLS55 during July.

Some of the big price jump going from Renntech 5 > 6 is labor. Installation of the ECU, pulley, and airbox is apparently very quick and easy. The headers take somewhat longer. The throttle body and particularly new intercoolers are much more labor intensive.

Man, unless you were REALLY in love with your 55, it'd be a lot more cost effective to buy a used CL600 and do the Renntech Stage III.
