with these turbo motors the lower ratio will put less load on the engine, one guy runs 24psi...
he sees almost no boost in 1st, maybe only 10-12 in 2nd and doesnt see 24 until the top of 3rd, because he put in either 3.73s or 4.10s
i know my truck didnt have hardly any boost in first with the 3.73s
one guy with a ranger 2.3T went a lot faster in the quarter by ditching his 3.73s in favor of some 3.27s maybe?
