e/c =eurocharged. honestly if your running an n/a engine with zero mods you dont need a dyno tune. the e/c tune will net approx 20 hp and without any mods the dyno wont help much
from your original post it appears your primary concern is with the looks of the car not the speed. in oem form you can expect well over 200k in miles and with reg. maintence maybe more. it is one of the best most solid engines m/b ever built
