I installed a few bolt ons just the typical stuff, headers, off road x pipe, bullet race mufflers, under the axle, lid, filter, bellows, most free mods, t hinking about the ftra in the near future and ill be removing my AIR and EGR in the next couple of days. I was thinking about just getting a dyno tune instead of just deleting the basic stuff. Just wondering how much rwhp you all thinkid pick up doing the dyno tune...
i put down a hint over 340 rwhp hp about the same in torque.

also i have nitrous...do i have to get a dual tune ?
