ESS remap after exhaust install?
so I just recently got my Eisenmann quad race exhaust but feels a little sluggish thru mid to high rpm especially in 3rd gear. Im running on ESS stage 2 for my 35i and was wondering if I need to remap from ESS to get a better tuning. The sound is great but I wasnt ready to give up power just for that.
