FREQUENTLY ASKED QUESTIONS

Critical items: ample fuel of the SAME type you'll run after tuning (TOP TIER gasoline recommended), properly sized injectors WITH DATA, fresh spark plugs gapped to spec, fresh oil and proper fluid levels (no leaks — $75 clean-up fee applies to spills), working lug nuts + wheel lock key (wheels come off on our Mainline dyno), and a clutch that doesn't slip (a slipping clutch ends the session).
