Alright, its not the absolute first, but the first since the TT kit was installed.
My roommate and I were coming back from dinner, just cruising down the highway around 80. She and I were just talking, when a 2002ish Mustang GT with a stupid loud exhaust about locked up the brakes to stop from blowing by me.
So he keeps jumping on the gas to intice me, so after approval from my passenger to go, I slow down to about 70 and downshift to 4th. Holding the revs just out of boost, he downshifts as well, and this is when I hear the whine of a supercharger, so I get excited planning on a fun run. He honks, and he gets a SLIGHT jump on me, then I hit boost, the wastegates start dumping, and all hell breaks loose as I put about 10+ lengths on him, I let off at 120 and he stays on it until he can catch up. 2nd run, we slow down to about 50, so I can grab 3rd. It sounded like he grabbed 2nd this time, again he honks and gets the jump, as I had bad timing. He got his rear tires at my door before I started pulling away. This time I let off just over 100 and was even further ahead than the first time.
He ended up getting off at the same exit as me, and pulled along side at the light. Ends up that he has a Vortech supercharger and other bolt ons, dynoed at 350 whp. He asked what I had, but all I said was TT, but no hp#

. He just kinda shook his head and turned the opposite direction. So I continued on my way happy with how its running now.
BTW... This was late Sunday night on a nice empty highway, no weaving through traffic or anything.
