I don't plan on messing with mine.
I did experiment with full throttle acceleration on wet pavement before the Cortex..
Oh yeah, there is definately SOMETHING holding the Hemi back,,,,
At 30 mph, my little 5.3 Silverado would bust loose both the rear tires almost instantly on wet pavement if ya punched it. (3.73 locking diff)
From a dead stop???? Well, DUH!!!
The OEM TM on the Hemi won't allow such things,,,
Before the Cortex, I got out in a parking lot in the rain (actually behind the stores and not in the parking lot)and planted the skinny pedal for about 10 seconds,,,
The truck would accelerate, slip just a little back and forth in the tail, but it would never really bust 'em loose. (3.92 limited slip) Without the TM, I'm sure it would be all over the place,,,,
I have not tried the same 'test' with the Cortex. I'm not looking to boil down a set of tires on a regular basis, either!
I do not know, exactly, why controlling the TM is a 'desirable' thing from a performance standpoint. I can only guess that if the TM is set to 'maximum control/safety' (OEM) that there might be a chance it could pull back the throttle under certain heavy acceleration conditions.
A 'little' tirespin when racing is not a bad thing. Also not a bad thing if you are muddin,,,
I don't do much of either, so I'll probably be OK!!!
