bootlife, make sure to get the tb spacer ported to add another 10 ft lbs of tq. Also, make sure you get the most expensive shorties you can find. Remember the more money you spend on one item the more hp gain you get. to get more tq from you're exhaust, run a 1 1/2" pipe straight through with no cats or mufflers. they restrict you and the smaller pipe helps keep your exhaust flow constant. dont worry about a custom tune. anyone selling custom tunes is a liar no matter how many years they have been doing it. I highly recommend the 78mm BBK tb, its worth every penny. even though, the net gain is almost zero, it feels more powerful and thats all that matters. hope this helps.
