Having a problem with boost control on one. What's happening is that it makes the commanded or at least very close to the commanded on the first dyno pull, then consecutively drops boost off with following pulls. Will eventually only make 5 to 10psi. Have tried everything with limp settings to the point of all but shutting them off completely. OS has no effect that I can tell. Don't see anything in the log limiting it - no throttle closures and so on...
Car has a haugn turbocharger on it - don't know exact sizing. Has BOV, intercooler, CAI with MAF in behind filter as stock, catless exhaust system.
Any help or insight on how to properly do this is greatly appreciated.
