Oh the glorious life of a 2500 series SUV owner....

I asked Crown Performance for the correct part number before I ordered, knowing these vehicles are finicky, especially 2011+ since the trucks changed but the SUV's didnt.

Looks like my brake line and air spring install is going to be postponed a few more weeks

Had a busy day today...

First order of business was uploading my AutoCal tune and going for a test drive. Ill tell you what, I'm not a WOT type of driver, but HOLY SHIT :head3:

For those who haven't been through the process, during the initial data logging process you're supposed to do a few WOT pulls for 3-4 seconds. I did these puling onto a highway from a slow roll so I can get a solid 4+ seconds without breaking any speed limits. Now dont get me wrong, my trucks not a race car and I know that, and have never felt held back when on the throttle. But while doing these WOT runs the truck would start dogging it around 70mph, like i was pulling a large trailer up a grade.

After installing the tune today I went for another test drive and did another data log, as they request a follow up file to check things out. I did the same WOT scenario, but I'll be damned the truck was a whole different beast!! It did not stop accelerating until I let off the throttle just shy of 90mph. And this is still with stock 3.73s and 35" tires. This is going to be a fun truck (funner?) after the 4.56s go in next month.
