In some cases with a big compression bump we have had to lean maps out a couple percent. But overall the map you are running now should be fine.
Do I need a new PCIII map if I just goto a 11.5:1 cp piston?
Was just wondering since I already had a dynoed map do i have to have it retuned if i go from a stock to a 11.5:1 cp piston? elevation 2,000ft i believe
thanks
thanks
