ok since its tax refund time, what would be better for me should i order the sct chip with there mail order tune and when i get cams/heads/manifold take it to the dyno, or should i go with the sct xcal2 tuner. ive heard that the tuners are more for people with no access to a dyno. if this is true should i just get a chip since i have access to a dyno.


get a tuner then head off to get a dyno tune
