$300 to $700.
so sounds like youre onto a winner, as long as they come recommended, so one familiar with wolf's would be better. also make sure theyre familiar with how to make good power with a 4ag. that = not being scared to run a lot of timing advance.
dyno time is always $100/hr at least. plus the tuners time, plus set up. i would never want my car on a dyno unless i have $400 to spend on it, you dont want it rushed, or cut short.
1 other thing make sure the car is 100% ready in all other ways, no leaks, no over heating, everything is tight and ready. it has got to be about the most annoying thing in the world for a work shop to receive a car to be "tuned" when its not even mechanically sound.
