this only makes sense at surface value where daily drivers must be reliable and track cars may be as rigorously required to be reliable. a daily driver is floored to redline occasionally. a track car is floored to redline at every given opportunity. so which is going to push the injectors harder?
anyway, an OTS stage 2 map should not require any fueling upgrades. i know its a different car, but i ran the cobb ots stage 2 map on stock fueling for 2 years with no problems and complete peace of mind.
