Dyno numbers in!
2007 Mustang GT w/Pypes Mid mufflers and Brenspeed 91 octane tune. It was running lean the first run, so we richened it up 4% for the second run and it could stand a bit more fuel still. I think I might've accidentally leaned the tune out when flashing the XCal once and not realized it which explains the lean condition.

You're saying you had the a/f LEANER than 13.5? Personally I wouldn't have it as lean as you do I'd stick with 12.8-13.0 at WOT MAX. But that's just me I don't like possible detonation.

I love the sound and construction of the system for the price, but I'm having some rattling issues with it right now and I think it's because the welds weren't finished inside the mufflers. I'm contacting them today to see what they say about it.
