Changed to latest tune 9r14 yesterday and drove 268 miles last night at 65-72 MPH (most of the time), averaged 20 MPG, with extreme tune on a 2003 6.0L F250, Calid VXAP1N6. EGT reached a max of 1200 when punched to 95, and boost was variable, once went to 40 psi on a small uphill grade, mostof the time with WOT reaches 35-37psi. Highway response is GREAT.
One issue - engine seems to starve for fuel at times, at about half throttle from about 40MPH, and WOT at 70-95 MPH.
Played with the truck a little today and it seems to starve for fuel when peddle pushed enough to force a downshift, speed does not seem matter.
No downshift and all is steady,smooth and strong.
