What RPM does it happen at? Random or usualy the same? Does the boost gauge read a loss?

rodney/dave

its prety random doesnt really happen at any certain revs ,sometimes at 2000rpm ,then tonite it changed up and was just flat at 4500rpm like i wasnt moving ,dont understand it makes my rx7 seem very slow lol

Boost solenoid on the 2nd turbo? Perhaps a vac line split?
