i have a brand new stock 2013 335is, i just hit 1300 miles, how much horse power would a JB4 G5 make on the stock 335is? I dont plan on doing any mods soon just the JB4, what map could I run. I am currently stationed in Italy and the octane is a lot higher here with regular gas at 93 octane. Do you guys do military deals or even ship to APO's? THanks.
