Jared (the tuner) was impressed with the computers ability to adjust for the higher exhaust flow. Then we put on the Stillen G3 and did a few pulls. It produced 310hp/251tq before the tune but, the air/fuel was way out. Then he tuned it and it still produced 310hp/252tq but corrected the air/fuel ratio. So basically I picked up 9hp with the Stillen G3 ($550) and a tune ($450). Unless your willing to pay about $1000 for 10hp its not worth it.
