Just got home from a visit with Doug @ BamaChips. He installed the tune then DYNO'd the car. With nothing more than the tune and an X pipe it dyno'd at 250rwhp and 260 ft. lbs.
with the 89 octane tune, an improvement of about 10 hp. I had almost a half tank of 89 so I'll have to wait until I can fill up with 93. It still barked the 275/60's in 2nd and 3rd.
I AM IMPRESSED. Getting a C&L CAI and axel backs next. Anyone give me advice on what name brand will give me good deep sound with out much drone? Your input would be much appreciated.

From one old man to another, FRRP's Stingers will give you the sound and the look you want. 4 inch dia. stick outs on the rear looks good.

From another old man, if you do not want any drone get the Corsa mufflers. I have these and they sound great with zero drone. Doesn’t Doug make a great tune.

The Borla (Ford Racing) stingers sound awesome and are by far the best sounding mufflers on the new mustangs. However, the drone in my car with the top up is
flat ridiculous!!![:@]

If they didn't sound this good, they would be gone. I'm sure it's not as bad in a coupe because the insulated metal roof... with my top down, it's not bad at all. Thankfully, it's not my daily driver....
