Well i was messing with my intake the other day and when i took it for a ride it only hit 1 bar and my cel light came on. i have a forge mbc, and a aem shortram, and i checked that by regreasing the ball on the mbc, and i also checked my bov. what could cause this drop in boost. im thinking it is one of the lines that run from the mbc. Ive searched but i havent found anything yet.

 

what exactly were you doing when you were "messing" with the intake? Did you plug your MAF back in?

 

1.0 BAR shouldn't throw a CEL since it is below factory boost spec...
