Im getting ready to go to kcir this weekend and was wondering if I should advance my timing with my xcal2 and if so how far my car is n/a with a 89oct tune for 24# injectors.

good 'ol butt dyno testing:
i'd say advance it and road test it in 2 degrees accross all rpm bands and then take it for a ride to determne if any detonation has started occurring.

if you have a wide band o2 sensor setup on the car that would absolutely be best.
