There is compensation for road crown but exactly where is what I do not know. The front axle has a small amount of 'cross-caster' dialed into it and that has something to do with it.
As for the reduced wheelbase on passenger side, it would be nice to know how this is accomplished.

It's a commuter, so I don't want to go crazy. I'm leaving the suspension alone, and I don't plan to do exhaust for at least a couple years. I might install a better intercooler or at least a ring to channel more air through it

Federal law, they can't void your warranty unless they can prove your mod caused the problem. I'm looking at a CAI and a canned tune. Trifecta has a new tune for these that's transparent so GM can't even see it. Adds +44hp at the wheels and +51ft-lbs of torque. Also reduces shift time by 67% and reduces fly-by-wire throttle lag.

Their canned tune for the 1.4T is an in-stock product. No custom work on their end. I looked at Bad News Racing, but their system increases the flash counter on the PCM and voids the powertrain warranty

You will still have to go through the same process I am going through. Our tunes from them are off the shelf as well. They will still need either your VIN or serial number on the ECU. After that, they take the off the shelf tune, load in your info and send back the cal file. They do a good job but take forever. Vince is impossible to get a hold of so I have been using Michael instead and it has helped.

Gotcha. Thanks for the heads up!
On the Jeep side of things, I also found the problem that was causing the J10 to die at seemingly random times: The wire leading to my ignition coil was shorting on the valve cover. I found it when the primary wire harness caught fire in front of my eyes...
Three wire splices, and the J10 is running like a top. Now I can sell it and put some of that money into fixing the YJ's cracked transmission housing, and maybe a new set of 37s

Got my 784 injectors and installed them not too long ago. Finally misfire is gone and jeep is driveable again. Can't believe the crap that builds up around the Injectors.
