2002 7.3... I had a super chip for a little bit then I upgraded to a DP set up... With super chip I ran a 15.8, with the DP I can't get it below 16.2.... No boost leaks I'm pushing 27psi... All vitals good.. Any input would be appreciated.. I'm kinda disappointed to tell you the truth
DP with what tune? if you're truck is all stock you may actually make less power on the 120 or 140 tunes. I tested it when I was auto, consistently almost a full second slower than with 80. I'm an E99 with a somewhat weak HPOP

im not blaming jody or the dp folks whatsoever... i emailed them for their input, probably get back to me on monday... tire pressures good... everythings good... only thing i cant monitor is fuel pressure or fuel rail pressure..
Possible that the tranny is slipping a little with the added power?
A small amount of slip would be difficult to notice, but it would show up at the track.
What were the the mph of the two days?
PIS 175/80's, Van Turbo with EBPV, BD Billet Wheel
Lots of money spent at RiffRaff
Holley fuel pump, in tank mods, crappy riding leveling kit, DP-F6, 5 Gauges+Edge CS in dash, CB radio in Dash, over 100 goofy little mods
Still pretty slow, just less slow now.
