Which will give me more power I know the SCT will give me alot of things but right now i want power first. So which one do you guys think will give me the most power? How much power can i expect?

long tubes about 10rwhp and plenum/tb combo( accufab ) 5-8rwhp, in addition to underdrive pulleys i have just done intake and exhaust, dyno'd at 263rwhp, i did accufab 75mm tb and plenum with a densecharger cai, and i did a full mac exhuast, so i gained about 35 rwhp with just those mods
