I did some of this a while back, but haven't gotten around to posting.
I attended the 034 Motorsports Summerfest again. This time I decided to jump on the dyno. It was in the mid-90s when I hoped on. It is their heartbreaker of a Mustang Dyno. Overall, I was pretty happy with the numbers. The pulls were nice and consistent.
I was also able to get $100 off their DSG tune. So I bought that. The normal D mode feels much sportier. It feels like a good mix between stock D and S mode. It feels more how the car should have felt rolling off the line. Perhaps my favorite feature is I can see what gear I'm in while in D or S modes.
That being said, after I had my DSG service (pre-DSG tune), I started to get a weird jerking when going from a dead stop to applying gas. It did it almost every time I let off the gas. Now that I had the DSG tune, it does it maybe a 25% of the time. Not exactly sure what is causing it. It makes me nervous for whenever I want to launch my car.
Also, driving home last night I blew a coil pack. I was doing fairly normal freeway driving and felt a sudden loss of power. The motor got loud and started to vibrate a lot. It felt OK over 40mph. But slowing down and coming from a stop was rough. The engine light flashed and the EPC light turned on. I was about 2 miles from home, so I limped it there and pulled the codes. It said I had a cylinder 3 misfire. Did some research and found other people with the same exact symptoms and their problem was a blown coil pack. Thankfully, with Amazon Prime I was able to get a new one within 12 hours. Swapped out the old one for the new one, reset the lights and now the car is running like a champ. I also bought a full set of four. I'm going to swap out all of the old ones and keep a spare in my car.
Lastly, ever since the coilover install, I've had a pretty nasty subframe clunk that has gotten progressively worse. It isn't horrible, but it's making me want to do some subframe work for me next mod. I just really don't want to redo my alignment since I just did it a few months ago. I hate paying for that. I might also wait and do a FSB since I'll have the subframe off.
