Good luck

The wastegate pill is internal isn't it? Or maybe i'm thinking about the wrong line.

fyi I had the same problem with my fd. The more mods I added the higher the boost spiked during secondary

Well i'm only running DP and 3' catback with stock cat, so i'm not sure where it's comeing from. A buddy of mine is selling me his Apexi AVC-R so i'll try to figure it out in the meen time but, i don't know enough about turbo's and or vac lines to get it. Unless i stumble across something while i'm taking it apart.

I'm not sure where that is. I'll take a look in my factory service manual and try to figure that out though. Thanks for the help by the way.

Try to put a line directly from your primary turbo into the wastegate actuator with no pill....you should only get to 7PSI.

if it reaches above 7PSI.....something is wrong with the wastegate.
