i think the torque tubes come with a free dyno from lloyd. i have the lloydz airbox but i wish i had shelled out the other 2 bills for the TT's especially if going to lloydz was an option for the free dyno.
just a thought
the loydz airbox made my torque and power curve change alot. it makes me want to run it to red line all the time. it doesnt have the grunt it used to have on low rpms. the top side of the rpms is awesome tho. im saving to get some TT's. really wish i had just done it to start with.
