RENNtech E63 W212 runs 11.15 @ 126.7 mph with tune ONLY !!!
yourself in traffic when you saw fully facelifted & factory Supercharged 2003 E55 w211 & heard
it's blower whine then later realize it's got 150 more HP & TQ
Or even worse sporting a NON-turboCharged v12 SL, then see a
V12 BITURBO facelifted SL & realize it's got DOUBLE your Torque.. Last edited by Thericker; Apr 17, 2012 at 07:49 PM.
