This Friday I took the R/T out for a short drive to check the new tires and retorque the wheels to get ready to go to the track. Saturday night I drove to San Antonio Raceway for a test and tune. My tach decided to quit working so I had to shift by feel. The first pass was 13.01 with a 1.89 60 ft 98.4 mph. The second pass was 12.84 with a 1.94 60 ft 106.9 mph the third pass was 12.64 with 1.87 60ft 107.9mph. I think there is more in her but was short shifting by feel because of the tach. A definite 60ft improvement. More testing to come.
