Jerry actually called me today when he was about to take care of my tunes and recommended a 6600rpm redline which would be more beneficial because of my intake...so I said go ahead with it and 6600 it is. I guess you can go up to 6900 but I don't know about that for me haha

well I got my ECU and TCU back this morning...The car was sitting for just about a week so I gave it a good while to warm up and just run. Took it out for a drive to get some gas and check out the new tunes. I cruised around to let the TCU kinda adapt to driving again as well as the ECU.
My review so far:
After just one pretty quick drive around town testing it out all I have to say is YES. The car shifts noticeably faster and in combination with the higher revs seems to really pull hard on the top end. The manual mode is cool, being able to shift at really any RPM and having a quick response is nice. Its a cool and windy day here with air temps in the mid 50's so the car was running great. The tunes definitely unleashed the beast!
I'll update you guys after I get a chance to drive her around a bit more

New "S" and "C" are like two versions of the old "S". "S" is more sport and is a bit more aggressive than the old "S" while "C" is more "comfort". Both start in 1st gear.

Could you explain what the raised torque limiter part of it does, and does the C mode seem to be a smoother shift than factory. It seems like after my ecu tune, and s/c pulley upgrade it doesn’t shift as smooth or consistently as before under normal driving conditions. Would the increase in power and torque cause from the upgrades have anything to do with the symptoms.

Would this TCU tune prevent premature torque converter lock-up under moderate acceleration? I f-ing hate it when I am rounding a corner and go to accelerate out of it only to have the dame torque converter lock up and the car bog. So I end up mashing the gas to punish the car for its misdeed and then the transmission downshifts, which I don't want either.

Sorry but I can't remember how my car was from the factory. I got it 10 years ago. By itself C mode is smoother than S but is it "Mercedes smooth" after you added an ECU tune and a pulley? - no. Raised torque limiter is not for everyday driving. It's for more aggressive driving and track racing. For now, I'm not sure what it does. Still testing and logging.
Meaning?? Are you feeling any difference (seat of pants so far??)

There is definitely a difference, however I have noticed that while driving in regular S mode the car will occasionally bounce off the revlimiter when shifting at WOT even without loss of traction which I do not like.
With the 6600rpm redline...the car used to shift right before 100mph but now pulls through hard in the high rpms past 100mph which is amazing.
The butt dyno noticed some power for sure, the car feels smooth and shifts extremely fast

Recieved my ECU/TCU back yesterday and am extremely pleased with the results. Only spent an hour behind the wheel so far and have not played with C or M modes.
I had a SpeedTuningUSA flash from about 9 years ago with my EVO Sport pulleys and this tune pulls much harder in the upper revs. Low down torque is improved as well. Seems like the car does not down shift as early as it used too but it is probably still learning as all the adaptations were cleared.
Adam and Jerry were a pleasure to work with.

Even with the AFR spiking to 18 at shifts, with the last shift being at 106MPH I now run at 113.8-114.3 at the end of the 1/4 vs. 112.25 in the past.

Same thing is happening to my car... It's almost like you hit a wall for a second... and then it shift. It only happens once in a while though.

The area in red shows the drop in TP%, RPM and Boost while the AFR rises to 20+. This one is at 106 MPH. You can also see another shift point at 60 MPH that is also associated with a spike in AFR.

Jake, can this behavior be programmed out of the mercedes design? Also, my fuel is still at above 50 PSI at the shift points. Are you sure the fuel is being cut off? If this was a belt slip, how would I tell?

Happens to my C32 most of the time even after warm. If it was part of the original design I would of noticed it before the TCU mod. Only time I ever noticed something similar was on a 1-2 shift maybe once out of 500 shifts it would hit the rev limiter with the stock TCU. Now it happens on the 1-2, 2-3. Not sure if it would happen on the higher shifts as I have not done a wide open 3-4 (no space).
Is the problem because of the raised rev limiter and shift point or because of the faster shifts?
