. OBD way here too. unless you fix it by tune I'll have a code and I don't want to pay $1000 for tuner.
Local buddy of mine had these on his '17 SRT392 (Challenger) and his '16 Hellcat (Charger) - no codes......all good there. Ground clearance is nice - though......I need it on the rocker sills LOL.......whoops.
