it will make its power from 3k to when i shift. which is around 55-5600
it makes boost around 3k and peaks at 5 psi at 5k +
i have the SC trim, its the cheapest kit that vortech makes for the mustang. makes 5 psi which isnt much but you can feel it definatly.
i messed with the timing some and it really helped , it was at 10 and i put it at 13 and it liked it alot, i could tell a small power increase.
