Unlimited Boost + Raised Idle after turning boost to 17psi

Best bet is to pressure test the system. Basically you build something that can be put into the intake system, sealed and you can put a bit of metered pressure into. Met me see if I can find a good link for you. Pictures speak a thousand words.

if you have an air intake leak, it will suck in the "combustible spray" and the RPM will change. It's the "old time" way to check for vacuum leaks (back when everyone had a can of ether around).

Easy, take off your wastegate, weld the xover shut, and viola!

Hook it up after Turbo but before Intercooler ..
I use a engine leakdown tester coupled to a air comressor to reduce test pressure and to read % of leakage ..

Hey guys, just an update.
I did two things and now the car seems fine.
First I fixed a couple vac leaks, one back behind the manifold - and one on the blow off valve! The blow off valve has a flange that had come unscrewed.
Second I used the secondary idle adjuster to turn the idle way down.
Now the car is running great, its idling at like 900 rpm or so and the wastegate/boost controller are working flawlessly.
I think theres a good chance I still have some vac leaks, so next time I've got the manifold off I'm going to just replace the hose.
Thanks for all the help!
