I believe you should get the info from PTM about the shimms. GO are OK for 25% and the additional shim in the box it for during breaking in the engine.
Unless you bought a restrictor kit I believe it comes standard with the black 8mm and it's just fine with it. You can go to 7.5 or 7mm with it to gain some on the mileage if you like. For the truggy I'd leave the 8mm on or go to 7.5mm
