I just wanted to vouch for the incredible customer service. I e-mailed Lund on Thursday evening. A few e-mails back and forth and less than 24 hours later on Friday evening I had the tune in my inbox ready to download. Very, very impressed with the customer service. As far as the sound - just like everyone else says it's awesome in person. The videos just don't do it justice.
Two things to add that I didn't read (although I skimmed mostly through all these pages) are how rough the car shakes now and how hard the shifts are. When at a stop, the car will shake quite a bit, not a bad thing imo. And also I've noticed when in low gears (1st or 2nd) it jolts quite a bit, kind of like on a cold start up. When changing gears from 1-2 it also jolts a little hard. Went to the movies tonight and the girlfriend was embarassed because going through the parking lot it looked like I didn't know how to drive stick with how the car jolted in 1st gear.
All in all it was worth every penny. The sound is insanely awesome. All I have right now are Borla S-Types. I didn't want to go the O/R mid-pipe route with this mustang because it's been nice being able to drive and talk on the phone without yelling but now I'm seriously thinking about saying screw it and go with an O/R mid-pipe. Now I just gotta decide on the H or X.
Big props to Jon Lund and the best customer service I've ever seen.
Awesome. Don't worry, if I saw a loud cammed sounding mustang driving through the parking lot and it seemed to buck around oddly at low rpm I'd assume it had a crazy racing clutch, or a lightweight flywheel. The more mods the more difficult to get cars to drive 'normal' so it's all good!
