I just finished installing a techo supercharger with a 10 psi pulley, 60lbs injectors, boost a pump and colder plugs. I need to buy a tuner to dyno tune. I cant find a tuner that doesnt come with a tune. My question is if I order a tuner with a tune from brenspeed why would I get it dyno tuned afterwards if it already comes with a tune. Also if the tuner comes with a tune can I take it to get it dyno tuned without any problems? Any opinions are appreciated.
