Wow, '93 LE Editions are rare! Plus '93 is the best year of all for Dodge CTD's! Has the all mechanical Bosch VE fuel pump that's real easy to tweak. At that mileage it isn't even broken in yet!
May I very stongly suggest you install a Pyrometer ASAP? That monitors combustion chamber temperatures, at the exhuast manifold just pre-turbo. Yours is probably aftercooled but regardless, if EGT's [Exhaust Gas Temperatures] get above 1,250-1,300 degrees sustained on a hard pull you can melt pistons before you can even shut the engine off, no warning before it's toast. Lots of bull out there about guys claiming 1,500* no problem, and 3 times as many that can tell you about toasted engines at 1,300*.
Also a Boost Gauge is fun, to monitor what your turbo is doing. The more turbo boost the more fuel you can add, easily with a VE pump, and safely with an Aftercooler and Pyrometer.
If it's an auto be mindful of fluid & filters, even anal, 'cause the Cummins is pushing that tranny to the limits. They like to eat torque converters. A LARGE auxiliary tranny cooler is a real good idea too.
If it's 4WD the front axle u-joints require religious attention, not well designed, a weak spot.
