Hi. Glad to have found this forum. I have a 13 explorer sport with a few mods. Currently I'm running an air raid cai, Livernois tune/exhaust/down pipes, thermostat, cooler plugs, Alky systems meth injection. Planning on some serious upgrades soon in the turbo dept and fuel delivery. So looking forward to hearing what everyone has done to get massive power to the ground. I'd honestly like to do a quad compound turbo setup, but not sure how well that will work for my vehicle.
