Yes,
This is everthing I have done to it: Superchip, AFE stage 2 air intake, Bullydog 4" turbo back, Bullydog Outlook, ATS Five Star TC. I haven't had any problems but after a long trip pulling my trailer it doesn't want to start as easily any more. So I hooked up my superchips and did a diagnostic test and it came up with those two codes P0603 and P1211. Any ideas?

Is it only hard to start when the engine is cold, or all the time????? Cold hard starts are simply a glow plug system issue. Test your relay and/or glow plugs.
0603 is caused by the tuner. Ignore it.
1211 is more than likely caused by the tuner when you are hard accelerating. It happens to a lot of us and it doesn't hurt anything. The code basically stands for "high oil pressure higher/lower than desired" and trips after 7 seconds of lower or higher than called for pressure. Many HPOP's have a hard time supplying oil that a higher hp tuner or chip calls for, and you set the code at WOT runs.
If you are having problems starting even when the engine is warm, then you need to find out if the 1211 code is the issue. To check and make sure, clear the 1211 code and make sure your tuner is on a lower hp setting. First check the oil in the HPOP by popping off the cap at the top of the reservoir. The oil level should be within a 1/2 inch from the top. If it's ok, then put the plug back in. Next, crank up and drive NORMALLY, no WOT runs at all. Return home and scan for codes again. If it pops up again, then you may have IPR or ICP issues which is causing your hard start. If not, then you have fuel issues.
