Staged up at a track a couple of hours up the road from us. GREAT TRACK (Bradenton)… brand new surfaces on the lanes. Sticky as hell!
Got out, opened the dumps and on the first pass after a quick burnout, the car literally left in third gear… NEVER DONE THIS BEFORE.
But I stayed in it, just to see what it would do and it didn't disappoint… it would not upshift into 4th. (I usually leave in the third gear slot, but it's never actually left in third gear before.)
Second pass, I picked up a NASTY wheel hop on the burn out. It did this ONCE before, two outting ago, when I had a passenger on the early pass (decent track prep at our local track), but didn't do it again once he got out and hasn't done it since… but at launch it did it again, very nasty… got right out, eased into the torque getting back in and as soon as it hit the power curve, it began hopping like mad… I stayed in it this time hoping to power through it, but soon realized that wasn't going to happen.
Nothing has changed in the physical setup. Same everything… same settings on the shocks.
What has changed is the PCM and the tune, but the programmer says that he didn't do anything but change the shift points, which are MUCH better, to be sure.
Any ideas?
