...Hmmm and I have quoted that as fact to my mechanic....so this may not be true that after initial engagement at 2200rpm its on all the time...ok..and the relief valve statement above...I was unaware that there was one. I do have those symptoms that you describe about the boost building and keeping the RPM's up well after you have released the throttle. I thought only turbo's had the waste gate and thought that our SC 'ers were without any pressure releasing mechanism.
..Please elaborate ...Thank you..
