Stock "SCT tuned" hp vs bolt ons, 4.6 2V

[OV10stang]

Just for anyone wanting to know: General info, typical stock "dyno tuned" hp vs bolt-ons(numbers vary from car to car). As you can see, not a huge difference in peak numbers, but you have more hp up higher in the rpm band....shifting at 5800 to 6000 really makes a difference at the track.

i would still shift 5500-5600 tops in a bolt on 2v no matter what. dont raise your shift points unyil you have some cams or heads... i had about 500 passes to prove it, along with a bunch of friends with quick 2vs and the same results
