Actually thats an excellent idea. Have you noticed decreased turbo lag (spool) after first gear?Clint said:This is an Apex Industries twin chamber. Apex claims the way they made this valve it will handle low boost as well as high, both at the same time. However, I set it for higher boost and am running the bosch valve for low boost and to aid in releasing pressure in high boost. This allows my turbo to spin freely after the throttle body closes. It spins for a long enough period that it is still spinning when I get back on the throttle. I had to make the flange for it.
