came with a Hyper ST i bought, no idea how much fuel has been through it im afraid
runs ok just quite hot which they all seem to do, may just need a different plug to help things, before i removed it, i reset it back to factory settings, but by that time id already bought a new engine so never ran it to see if it was just the tune that was out
im running a different engine now and was gonna keep this as a spare, but for how much i manage to get out to use my cars i may aswell sell it to someone who could use it
after run oil put in before i removed it from the car, air filter will come with it too
