apr 1+ inconsistent boost problem
 

After I got APR 1+ installed I have been having a problem. For periods of about 10 minutes my car will randomely not boost past 8 or 9 psi. This has happened twice to me so far. My car will then suddenly begin boosting normally to a little under 20 psi. I have the n75j valve.... do you think that it might not agree with apr 1+ because it is already asking for such high boost?

you just got the 1+ so id give it a couple weeks to adapt before you start getting worried.
It is possible the J valve is not a good match with the 1+ software.

ok now I switched the N75 back to the stock one(made sure I put it in the right way... long tube into the intake and the wire pointing up) and now my car is in limp mode boosting no more than 5psi. I restarted the car... made sure everything was still plugged in right and tried it again... and still in limp mode. What could cause this?

you have to reset your ecu by unplugging your neg battery terminal for a few minutes before you get out of limp mode. sounds like you might need a mbc.

full boost is nice... unplugging the battery worked. thanks onepoint8tee.... and jeff
