I am contemplating either the Powerchip ECU or Evotech ECU/TCU combination. Powerchip will custom tune my car on a dyno as will Evotech but the difference is $800 for the TCU upgrade.
Can some tuning expert explain what a TCU upgrade will do for a C55 and why it would be necessary?
I know that my car shifts too early (upshifts from 4th to 5th before Max torque is reached or downshifts from 4th to 3rd causing a torque spike) but I don't know if the ECU or the TCU will address these issues.
I heard that the TCU upgrade simply removes the limiter that protects the tranny from too much stress if the car has too much power.
My current SpeedInnovation's custom ECU upgrade included changes to the shift points (higher rev limiter) but does the TCU do even more in terms of unleashing more power?

Robert.....Robert.......Robert.......
I know for a fact SpeedInnovation has the latest files for your car they have a Star Diagnosis and they have the latest updates for any mercedes vehicle. Before you go on boards and think maybe you should ask them first. They got their Dyno Dynamics BTW.
Also they know how to modify that blower cause guess what he what right from the begining imagine that!!!!!!!. BTW did you see Techtunes R129 sl500 thats hits 12s...... what was your time slip again. Hmmm where do you think it came from.....CoEngineered
And last but not least SpeedInnovation really wanted you to stop throwing your money away on that system you keep trying to modify and make that promised number and put a oem55k motor in it of course with a few mods say 700hp C55 but you wont step up Im sure that oem 55k stock is putting out much more than you are getting in your highly modded state.
If anyone is interested in a oem 55k motor with less than 1000 and wants to swap it into their c55 call speedinnovation they know how to do the swap and wiring and the ecu so it is a seemless transplant.
and then call Robert Out and lets take it to the drags.........enough said.

If it was me and I had the same issues you had from the begining then I would dump what you have and go oem55k for max power . It is a better built platform to start with.
However Speedinnovation knows how to fix your blower and your problem..or if it your quest to have a c55 that blows the socks off of anything on the road then they can do that as well
Question is what do you want to do?
Why cause they can do either of the two so instead of putting your guard up listen to advise given properly.

IMOP You'd be better off just going with the Kleeman S/C setup vs installing the OEM 55k motor. I've alreadt inquired about all of this. It's not a 1,2,3 install like what's being suggested here. There are also many other parts involved,heatexchanger,water lines,pump,the engine mounts and brackets are entirely different as well. Amd don't forget the electronics. In the long run I'd either get the HPS kit modified(taking a chance) or just go with the Kleemann S/C kit.

My other option is to buy the Kleemann kit from a few fellow members, however, the new kit is not much different and the old twin-screw is no longer supported by Kleemann. They will not provide the ECU upgrade for it anymore.
Jessie is still trying to put together a complete E55K package including ported heads, pullies, 80mm throttle body, Cooling kit, X-pipe exhaust, ECU while still utilizing my Kleemann Headers, Cams and Cats for under $20K. Vadim also advised against taking this risk but Jessie says this is an easy slam dunk with 100% success rate putting out 700hp. He now owns www.Gintani.com. This E55K motor has less than 600 miles on it according to Jessie.
So these are my 3 choices. I need some advice again on which path to take.

Not an AMG :(
Jessie won't retune my HPS kit but Mechtech/HPS will. They actually have a programmer in Germany that flashes the ECU and sends it back to Jim. It would cost me $1500 for a custom tune with all my additional mods. There still needs to be a fix for the intake/inlet piece of the HPS kit that is restricting the air from entering the inlet of the blower itself that must be reworked to get the kind of power the Callaway Vettes are getting.

Someone who is as determined as you should scrap all of this current project while your motor is still functional. Get yourself an E63 (or C63) and explore the TT possibilities.

so you are saying that 700 hp is not possible i beg to differ. I heard gintani finished a ported head,supercharger, and some special hardware and tuning on the SLR and it made another 90 horse at the wheels on the dyno. I think they may know something other companies may not know or is beyond their knowledge at the end of the day their work is very high end custom.
also sir take notes as the new 722 Slr is over 700 hp
