Should I just call streetflight, tell them my mods and the fact that my catback will go in also and have them burn me a chip, then tume? Or, should I get in a dyno run first?

I figure the initial dyno may not be 100% necessary since the guys at Streetflight would be able to get me within 90% of peak without it and then save the money for later additional tuning.

Or am I wrong?
