Does there have to be a CEL if my car goes into limp mode? I had my clutch done today as well as a lower control arm. After I picked up the car it was boosting fine (15-16) then I came back to it and it was only hitting about 5. Anyone know whats goin on here? I have a OBDII scanner at home but im at the wifeys place now so i can't check it right now.

Sometimes it won't show a CEL, but it will throw a code. Scan it.

scanned it and no codes. Could my ECU have been reset to valet mode or something while my car was being worked on? I have the GIAC 4 program chip.

Where did you get it worked on? Also what year is your car?

If it was a year that can be flash loaded and you brought it to a dealer they possibly could of overwrote your GIAC tune.

Nah it was my mechanic who did it for me. My boost came back this morning but now it only hits about 13. It is 90 degrees and humid tho so could this be why its down a little? I know humidity can hurt boost pressure but no sure how much. Cars a 2000 by the way.
