I need to log my truck 2nite to check some sensors and find out why my truck has suddenly got laggy, blows tons of smoke on the bottom end, doesnt build as much boost, doesnt rev as fast, has a choppy idle. What do you guys suggest i logg? What sensors could cause this? Maybe my CP3 took a shit?

What do you mean rail press and current? I have the dsp5 switch but not sure what you mean. What sensors should i check? Already changed MAF and MAP. Alligator said something about the BARO Sensor?
Click to expand...

Baro sensor if its bad your Baro will be out of whack,Ive heard of some plugging up with mud and only partally working...If your wanting to see if its fubared just log baro and see if it moves,It should not move around and read close to the barometric pressure of your area

Rail press DES and Act ALSO rail current in milliamps des vs act:)

logged BARO2PSI and it stayed at 11.9 the whole time. Is that normal? My RAILACT was alot lower than RAILDES but that was expected. My cp3 is comin out asap.

i guess actually it wasnt that bad, My DES of course was 23,786 and my ACT stayed at 23 most of the time, dropped to 22 and 19 a couple times then back up to 23 before the run was over.

At 90 mph i was at 27 deg of timing, ECT was 169, IAT was 81 and MAF was 62.3 the whole time. The BARO stayed at 11.9 and never changed. That frame was at 3465 RPM's.
