I'm now up and running again with my 4th tune revision from VMP and keeping my fingers crossed that I wont experience any more stalling. 2nd and 3rd revision resulted in at least 10 more occasions of stalling. I was finally able to capture the stall in a file small enough to not crash my cheap laptop and allow me to send it through Hotmail. Got the latest update yesterday evening. I must give props now to VMP as my issue with the initial delay was a mix up of my customer # with the owner of my local dealerships stage 3 Roush (I ordered the upgrade kit through them). They have been very responsive to my issues and questions and even sent me one of the tune updates last Friday at 11PM?! Any update on your issues OP??????
