Just looking for info and feedback on the SLP pipe and the stge tuning kits. Have a new PC 800 on the way and plan on doing at least a pipe. Im considering having the cylinders done as well just dont want to make it unreliable. Had the stage 2 kit on a 2010 m8 and liked it for the most part just didnt like haveing to add octane booster. Thanks for the help
