Mustangweek Dyno!

I got my car on the dyno from pro-dyno on Friday during Mustangweek. She put down 310 hp and 329 lbft! :D Just need 65 more hp and 70 lbft to get the 375/400 NA! Suggestions?

On a side note, the guy said my old tune was running me rich and I might have fried the coils. I was told to just buy a voltmeter and find out which coil isn't reading 8 ohms. Has anyone added aftermarket coils? If so are they worth it?
 
pro-dyno is a great shop to deal with. rob and dan are the best guys to deal with. i had a brenspeed tune which i loved, but once i got my pro-dyno it was night and day.
