From Evotech Motorsports and still in testing. But I've some information to start with. "S" mode is bone stock. Shifts, redline and all other stock transmission programing remains stock. Works in drive or manual mode with no change what so ever.

"W" mode. You can upshift manually quite early and it will hold the gear. It WILL downshift when you reach 1000 rpm, more or less, from the gear you are in. For instance, poking along in 5th and slowing. Reach 1000 rpm and it downshifts to 4th, reach 1000 again and it downshifts to 3rd, etc. until you come to a stop in which case it returns to first. However it won't upshift. Having been in 5th and now in first, without touching anything, you stay in first. You have to tell it to upshift. Upshifts are "on demand only". Therefore it keeps a minimal downshift function so you don't stall. I tried to get my car to downshift from 3rd by flooring the gas pedal but from 2000 rpm and perhaps even lower, it won't. I hit the warp speed button and it held the gear. I don't know the TCU's new "redline" but if it's similar to the Mopar LX performance TCU it's 6700 rpm. You still have the ECU redline which I believe is 6100 rpm. This TCU will not benefit your times at the drag strip unless your a shifting wizard and time the shifts perfectly. I was consistently slower. 2 reasons. Hitting the ECU 6100 rpm limiter or shifting too early. In "W" the torque limiters are reduced. Supposedly removed but I don't think so. The shifts are quicker and firmer but far from instant or neck snapping. Sporty is how I'd characterize them. You will feel a difference but it's far from a turbo 400 with a shift kit. You can shift on the fly between the "S" and "W". Switch on the fly and you find yourself in the same gear as when you made the mode change. Switch from W to S and immediately back to stock parameters and functioning. This is great for canyon carving or Dragon type drives.

Eurocharged to the rescue with a new tune with a raised ECU limiter. From my dyno pulls today it's at 6400. I couldn't remember if I requested 6400 or 6500 as I was back and forth on the decision. Now it may make a difference in the 1/4 mile. A little late on the upshift, no problem. More testing to come at the racetrack. The drag strip won't happen for a few months from now.
