Here's an interesting one, I go this twice in my Civic in the last couple days. Wasn't really boosting either, just barley touching boost and I got a CEL. Checked it and got a code 13 which is Barometric sensor circut/range malf.. Ever heard of this?

 

what turbo kit is it? Code 13 is in the ecu. Greddy kits have the problem all the time. Usually happens when revving in second gear when wthe car is still cold and not at operating temp for me. So I let it warm up and haven't had problems with it.

 

code 13 is usually casused if your messing with the ecu its internal sensor buiilt inside the ecu. Make sure you didnt tap any wired incorrect or anyhting like that.

 

Yea it's a GReddy kit, but i'm not usuing the GReddy piggyback, just some 440 w/ VAFC. Got me all worried now that I didn't manage to damage the ECU somehow! Guess I'll wait it out, see if it happens again, thanks
