Yeah, ok thats what I thought....... need more then block off plate when that gets yanked, cause you loose mid and low end without it.
I was same way thinking yeah restricting valve, remove it, once I did I could tell mid and low end bombed, but top end got a little boost it seemed. With a PCIII
and a good map or a custom tuned map you can really get it to scream, usually still have a little low end lag though.
Yeah that part probably does not add crazy weight and its sprung, but yeah saving weight is always good, so removing the valve since its titanium
and adding the stainless block off, you either broke even or gained a little weight.
But for sure, I would do a before and after dyno run to prove the increase and at what rpm.
