Hello Anyone -
Just dropped a COMP Cams XFI Xtreme ( 54-450-11 ) into my very stock 2003 Chevy Silverado 1500 LT 5.3L LM7 ( along with some performance springs, lifters, push rods and rocker arms ) and things just don't feel right while driving ( sounds pretty cool though ), anyway I'm one of those fortunate ( ? ) souls that has more money than time and would be oh so willing to pay for someone to take a look at my log file and get me pointed in the right direction for getting this thing tuned at least enough to drive it 3 hours to a chassis dyno shop in Idaho... 😅
Again, everything is stock on this truck ( including the o2 sensors and torque converter ) and the current tune is totally stock as well!
Also, I just received my MPVI3 device from HP Tuners a couple of days ago along with 2 credits so not real experienced in using it just yet 😉
Kindest regards and thanks in advance - Todd Oberg
