Got codes! DTC's. Dang.
I have two backpressure codes. It was sitting at 359-365 kPa for backpressure. Any idea what backpressure is SUPPOSED to be? I believe the scanner said it should be above 28psi and it's at like 55psi. Is that right? Where it should be?
Please help.

 Btw while I had the scanner (it's a SnapOn MODIS) on I did an injector buzz test and it said no codes, I also verified that my ABS sensor is still the only one messed up (since I messed it up), and the Air Bag code was only "Pad Lamp Inoperative" code so that don't mean THAT MUCH to me. It's the back pressure codes I'm a lil worried about. I figured it may be from my Wastegate Delete mod.

Oh and it said there was a KAM error code but it also said that could be from unhooking the battery(s) for a time, which I did when I put the S&B intake on.

Which KAM error 0605 or 0603 (something like that)? Give me the back pressure codes. Could be something as simple as being clogged with soot.

yes that's right for the KAM error, and the backpressure ones i think were p0470 and 0478 or 0473 something like that... i'll have to check, i wrote them down but i can't get to them at the moment. Thanks Dirk!

Yeah, post them up when you are sure. Also, it's important to know which KAM error you got. One is just saying you have a chip or programmer of sorts.. the other can be more serious.
