Mike Carnahan sent me a new tune to do some data collection off of, and asked me to put it into boost a couple of times so he could look at the data. I went into boost in third gear the first time, and then from fourth gear. I also let the car engine brake so I could get some data in those cells with higher RPMs but with vacuum in the manifold.

I think I hear the waste gates in the first run, but not sure. The MAP value is showing that I'm only at 144 kPa which should be only 6.2 psi of boost. There are supposed to be 10 lb springs in those waste gates....

This was the first time I've taken the car to 100 percent throttle.

Seat of the pants impression was that the car seems to pull a LOT stronger in fourth gear than third gear. Maybe just my imagination.
