hi,

i replaced a bad check valve yesterday and now my boost spikes to 15psi or more when the 2nd turbo comes on. i was wondering if there is anything i can do to stop this from happening? thanks

 

* Port the wastegate
* Restrictor plates for the exhaust

Just do a search for "boost creep" or "boost spike" and you'll see a few different methods for controlling midpipes..
