I just installed the Cobb AP, stage 2 last night. (Catless Megan DP, STi catback) The car feels alive now but I was wondering is Meth injection worthwhile on the stock snail. I plan on installing an MRT TMIC and PnP exhaust manifild this week before my Gadiel Protune. Should I bother with meth or just wait until I go with a bigger turbo (TD06 20G)? New turbo is atleast a year away, plus I need injectors and fp.
