Anyone know if these will hold boost? Probably around 15 lbs, strip only car.

Noone? I'm about to buy them and don't really want to make a big mistake...

I've done an extensive FAQ in the boost section that has plenty of builds to reference. More than one build was done w stock pistons, shaker comes to mind running like 20+ psi. Unless you just want new I'd go w stock as we know they work but that's me and I'm about to use an hx35
