ok so its been a while since i've had a stocker. i just put the stang back to stock form with a fresh rebuild. its running strong and all that. just wondering if anyone has done a tune on a stock car and had any benefits. would i be wasting money or is it worth it? the thing is bone stock except it has a 80mm pro m and 30# inj. left over from the 351. also had a 3 angle valve job w/a backcut. 2 1/2 off road. flows and all that. thanks for any advise.
