Because I'm a gadget freak and I wanted to.

I was using the deceleration valve as a second small blow off valve vented to atmosphere.
Then I sold it and took that cash and bought a nice looking black anodized chinese made turboXS copy 32mm blow off valve off ebay and mounted it under the intercooler. It works great with 2 of the included shims under the piston spring.
It's not needed but it reduces any chance of compressor surge in the turbo when lifting off the throttle quickly while under boost and I like the little woosh sound it makes venting some of the closed throttle turbo boost to atmosphere between boosted upshifts.

sorry to hijack the thread with this stuff here...
