S550 tuning special!

KLEEMANN USA is offering all MBWorld members special pricing on our ECU tunes for the M273 V8 engine found in the S550. Beginning today (7.10.12) for the next 30 days, software upgrades will be sold for a very low price of $795.00- a $600 savings! Typical gains are 20-25 HP/TQ, improved throttle response and removal of the top speed limiter.

If you have any questions feel free to email me: cory@kleemannusa.com or give me a ring: 719.473.6441

is it just the ECU thats flashed or does the TCU program change as well? does it require we disassemble the unit and overnight it or are there local dealers that can do the flash? would M275 be same price as well?

ECU only- it is not possible to program the EGS controller through the engine ECU. The EGS controller on these cars is integrated into the valve body of the gearbox, and is not easily removed.

Head over to the SL65 forum to see special pricing for the V12 Bi-Turbo tunes- they are not being offered at the same price, but they are on sale.
