Not getting any boost, boost reads vacume at -20 until i hit about 55 then go to -10. Hits 0 boost when I'm on the gas. Maybe 2 if I floor it and shift hard. cold pipe seems ok (I can't be leaking that much). I have a t4 turbo with a 2" outlet , exhaust side is 3" , Exhaust A/R .63, Charge A/R .50. Changed the intake pipe from 3" to 2" until the MAS. Thought the turbo couldn't fill the 3" pipe. Any Ideas what to look for?

Is this a new set up? What kind of waste gate? How do you control your boost? I made the mistake of taking out my waste gate spring when I added a boost controller.

I had that issue and it was my wastegate stuck open
