I was wanting to get gears and the predator tuner. but do i have to get the tuner professionally tuned or can i do it myself. I dont want to have to pay alot to have the tuner used. I mite go with a speedcal...????????

 

tuners are easy do-it-yourself tools, if you follow the instructions. I know that diablosport is pretty clear, and if you have a question you can email/call them too! Oh an gret 4.10s :P
