I heading to the exit ramp to get on the highway when I see this black 2005 porsche 911 TURBO ahead turning the same direction. I knew something was going to happen when we slowed for on coming traffic I could see him looking in his rearview at me. the highway is a three lane so I said to myself the minute way get on the road I'll jump in the far lane and hit it. We must have been thinking the same thing because the same time I jumped he jumped. I stayed right on his bumper until about 130 my tranny started downshifting so I had to feather it to go faster I got close to 140 but this guy was long gone I could see him about a 1/4 of a mile ahead zipping through traffic. Those cars are VERY fast. I was running 17# boost,t-44,93 chip by eric,342 gears. I dont have a fuel cut off in case anyone thinks thats what happened.
