I have a 99 SD, never had any problems 96,000 miles. I installed a Superchips 1855 tuner about a week ago set in to performance, was told this gave best fuel mileage. I've drove about 140 miles and when I started the truck today the ABS light was on and when I took off the overdrive light was blinking after a mile or two they went out. I then decided to take the truck back to stock when I did I checked for codes and it had 3 (a) P1247 Tubo pressure low
(b) P0500 Speed Sensor errors
(c) P0603 Internal control kam error
Could these be caused by the tuner or is there something I should look at, never before has the ABS or Overdrive started blinking. Thats what has kept me from installing a tuner before was thought of it causing problems, but picked it up resonable and decided to give it a try. Any thoughts would be appreciated.
the p0603 is comon when you change the tune...not a problem clear it and it come back if your plaaying with different tunes. the p0500 to my knowledge will not be set by the tuner. possibly a loose conection, you need to invetigate more. the p1247 might be an existing problem already but with the tuner cranked up and you got into it was showing that you might have leaks on the pressure side of the turbo. just a thought.

I returned to stock and drove it about 5 miles just now and pulled codes P0500 and p1247 were gone but had the p0603 and also a P1000 this time, another question will the tuner do more harm than good.
I checked for leaks couldn't find any tightened all clamps, tuned again performance drove code came back, is there anywhere specific or a good way to test for leaks that would cause the code P1247

you need to pressure check your system to insure that its sound (leak free). Were you flat into it, to trip the 1247 code?

I ran around town normal couple of days checked codes not there, then Sunday I was riding and kinda got into it and then checked and code was there. is this pointing to a cause not sure how to pressure check the system.
I would suggest that you get a scanner on it for live reads, check your map sensor readings, there are threads on the forum for making your own pressure check tool, don't take it past 20 psi if you do your own, (SAFETY). do you have gages to monitor egt, boost, tans temp, if you don't I would suggest that you don't use the tuner.
