Okay, another log run and the same results! Boost starts to drop off around 6300 rpm.
This time I paid close attention to what was going on and I think I have found the problem. When the engine gets to around 6K rpm the traction control light starts flashing which I think is pulling the throttle back. I need to remember to TURN THE VDC OFF!
You can see in the graph that the boost flattens out around 7.6 psi and drops off from there as the VDC is trying to correct the wheel spin. That MUST be it!
I feel like an idiot.........
That has got to be what is going on. It is cool that the rear tires are breaking loose in third gear at that speed!
I'll try again tomorrow.
