Didn't quite know how to title this, since I got the information about what the "Big Three Things To Do On A New Titan" from here. My 2014 Pro-4X was pulling to the left a little. Sure enough, Caster was out .5 degrees on the front drivers side and .7 degrees on the front passengers side.Camber was off .1 degrees on both fronts, and the toe on the front passengers side was out a .24 degrees. (at -.16). Nissan builds the truck without (WTF??) camber/caster alignment bolts. I had that done, drives great now. No more wandering in the lane, following the road crown, or slight pulling when you get on the brakes. My truck was at 15* timing from the factory, I had them advance 2* to 17* now. The information on here concerning factory Air Conditioning being filled low (Only 80% from the factory. Again, WTF Nissan?) was spot on. My truck was at 1.4lbs, the system holds 1.54lbs. So I had that done. The fourth thing I wanted to add, is idle speed. Normally, the truck is supposed to be at 650rpm, +- 50rpm. I wanted mine set to 700rpm idle speed (max factory allowable) to compensate for the low idle conditions and lack of off idle "pep" when I'm at a light with the AC going. Turns out my truck was running 537.5rpm idle speed (according to CONSULT) as the tech had to adjust it up 162.5rpm to get it to 700. So no wonder it seemed to get weighed down with AC and such going at a stoplight. Now, at 700rpm, smooth as silk. Once up to 35-40mph in town, I can just coast for quite ways now, where as before, the truck would not do that for hardly any distance. Stop and go is better now too, as I just let off the brake and the truck will quietly creep forward. The timing advance has been fantastic. The truck just seems to leap to 30mph like nothing. It's quite fun I have not had it out on the highway yet, so I'm curious to see how passing and on ramp merging has, if any, changed. Thank you TITANtalk for the recommendations!:big_grin: Very pleased how well they all turned out.
