I have an Xcal2, and I don't think my lightly modded Cobra is worth the $400+ for a nice dyno tune...I'm thinking about a $75-150 e-mail tune for hopefully like 5-10whp, but would it be better to just save the money for something else? I question the reliability/safety of the e-mail tune more than anything; I would be getting it from either RWTD or D'Agostino.
Thoughts?
