I'm dusting off this two year old thread to see if anyone found the limp mode solution.

I had this same issue and it got my attention as I can see a crash resulting from this. Gmd2003 my car is NOT FI and you've described what has happened to me to a T.

I too thought it was heat or possibly fuel related but I think it's vacuum that's part of the problem (or should I say a lack of vacuum). My car had seen several hard track days without issue but it wasn't until this last track day that I started to heel toe shift that this issue began to occur. My point is that between high engine loads, to heavy braking (with HT downshift), and then back to wide open throttle there's very little vacuum available.

Anyone ever figure out a solution for this?
