This spring I put a 3" downpipe on the car and a new pypes exhaust.
I'm running a stock actuator with a RJC MBC with a stock turbo.
Well last fall I had the boost around 14 to 15 psi according to my PL and 3 bar MAP. RJC was adjusted close to middle of the treads.
Once I completed the exhaust upgrades I took it out for a run and the PL was showing 22 psi
I now have the RJC on screwed in to one and a half threads and I can't get the boost any lower than 16 to 17 psi. Sometimes when testing I can get it creeping up to almost 19 psi. I also confirmed the high boost with my VDO boost gauge as well, so it doesn't seem like the sensor is bad.
Any thoughts or suggestions. I have a TTA intercooler with Dutt neck that I want to install, but I don't want to make my problem worse with freeing up more boost.
Thanks
Chris
