SCT XCal2/SF. I have the same prog for my 04' 250SD w/6.8 and its the best out there for the money. $380 at Jeg's. You can change lots of parameters, read clear DTCs and datalog with a laptop or just the unit alone. The programmer is also updateable by linking to the computer and downloading updates off the net. You also have the option of going to an SCT dealer and getting custom tunes made from dyno runs. I have had the tuner for 6 months and couldn't be happier.

I have used many of these on my 150 and I settled on the Edge Evolution. Gives you a programmable, realtime LCD display on the dash as well as all the other functionality the other tuners give you. Has performance tests like 0-60, etc. I'm very pleased with it as I now have all kinds of data at my fingertips.
