Ka-pow baby, that's what I'm talk'n about
Couldn't wait. Loaded the v3 93 perf tune and went for a drive. Here's the before and after. Both just flooring it from dead stop in 'D', 'normal' mode, no powerbraking, no anything special. In my dead stock Explo Sport with ~5,200 miles, the LMS 93 perf tune shaved exactly .5 sec off of my 0-60 times. "before tune" on the left. "after tune" on the right (ignore all the other stats, I was only after the 0-60 time) :
What you don't see in the numbers above is the change in driveability. Much less torque steer and much less of what I refer to as 'interference vectoring' by the fwd portion of the awd powertrain. It seems the rear wheels are getting more power sooner in normal mode and the shifts are now as close as they can get to our S5's DCS. Upshifts are BANG, bang, bang under WOT, but nice and smooth (but still crisp and firm) under normal driving. Still no rev match on downshifts, but hey, I'm a happy camper.
The 1-2 upshift under WOT is brutal, the other WOT upshifts are perfect. If the 1-2 WOT doesn't soften up a little as the trans relearns, I may ask Jaimie for a programming change. Or maybe not. I'll just use it judiciously (or not).
EDIT 17jun15 : the 1-2 shift has leveled out. All is well now. Nice firm upshifts 1-6 now with no drama. Perfect
I hope the 'turn bog' is gone. I couldn't induce it tonite, but there were our guys in blue all over the place, so I was taking it easy. Time will tell.
Powering out of a low speed 90 degree turn on dry pavement can now invoke the nanny mode in "normal". Finally it's a driver.
Bottom line - why did I wait so long? The only time the stock tune will ever go back on is if I need it to pass emissions testing in Harris county and NYS!
More to come regarding the PC and tuner load process, what happens to your readiness monitors (hint - they reset), etc.
Looking forward to the drive to work tomorrow.
