^^^^^^^^ and of course that kind of compression will liven things up a bit in preboost too, less lag. This is right in the middle of the pistons offered in the market so it would certainly cover that gap. And 8.7 - 8.8 is not insanely high and will still be realtively safe on 14-20 psi. If someone plans on running any higher than that then there are other pistons already available, right?
