On the main screen there is a PW gauge and duty cycle gauge. You can watch 
the duty cycle gauge to see if it hits 100%, and you can watch the PW gauge 
to see if it bounces wildly when the engine starts cutting out.

Unless you changed something you are still using my setup with a re-tuned 
map. I rev my car to 8,000rpm no problem both when I had 42lb injectors and 
now on the 75's, so it's unlikely that your issue is there. Verify you are 
on 1 injection per revolution on the 'constants' screen.

How about taking a quick log and sending it to me? All you'd need to do is 
fire it up, let it warm up, and slowly increase revs until the cut-out - 
that should be enough for me to find any evidence if there is any to find. 
Send your settings file too. We'll get this licked if I have to drive my ass 
back out there! I want to visit the Udvar Hazy Air&Space Museum annex 
anyways!
