I am not new to reading this forum, just new to posting. I have a black bullitt. I went 13.86 stock (no paxton), 13.77 with gears (no paxton). I put in the Paxton and WOW!! I cannot wait to get back to the track. I have the exact same drivability that I had before the install. You do not notice that there is a supercharger until you stomp the gas. The whole hole in the pan thing was NO BIG DEAL. I have basic knowledge and skills (I work as a teacher not an auto tech) and did the entire install myself. It took about 20 hours. Plan it right because you will have to send your computer to Paxton. I REALLY like them. I was missing one part (intake tube) and had a defective part (discharge tube). They overnighted the replacements no questions asked.
