I just set read everything.
Not still clear if the meth\water brings big gain in power, there is definitely some, but i don't think that 335d owners feel underpowered
My goal is to get as much life from my 335d, so i am interested mostly in clean and keeping my intake clean.
Hooper has mentioned, that there somewhere pictures of his intake after running meth kit with blocked EGR, but couldn't find them.
