My 2012 was laggy as hell even stock. I believe we have a difference in taste though. I don't do the large or anywhere close to large charger on the street. My truck now responds like a gasser just like I want. 4.56 gears and 37's. And I can run its balls off and not have any tranny issues. Which is where most 68 issues come from if you ask me. Geared to damn high.
Maybe the 14 tune helps the lag issue? Seems pretty decent to me. I've always been a huge fan of tiny turbos because I hate lag. And i've always had to fight the CO elevation. It ain't easy "ON THE MOUNTAIN!!!!!!"
2200 miles and def gauge hasn't moved. They either forgot to put emissions on mine or something is up. Can't wait for wheels and tires. Needs em.
Oh and scaled it. Half a tank weighing in at a mighty 7940lbs. Fat b!tch
I'll post a pic tomorrow. But I gave the dealership a handful of colors to choose from and what all I wanted and said go grab it. Obviously giving options on it that were a must and then ones I didn't care as long as we stayed reasonable on the price. They came back with the color correct but it was a 2 tone truck lol. Fitting so I kept it. Anyhow got a laramie 8.4AN radio, black interior, granite crystal with silver at the bottom for paint, factory 20's, heated/cooled front and rear seats etc. Very nice truck. I really really liked my '12 but I think I will soon forget about it. My wife called me all choked up cause she saw the new owners going through town in our 2012 LOL.
EDIT: AHall mine looks exactly like the pics you posted on page one except with 2 tone paint. Same wheels and interior.
