....When on the Flywheel Dyno my small block Chev's. maximum HP was @ 5400 RPM. What would be a good RPM to set the Tack shift light at??? Should I wind it past it's maximum HP??? Plus what RPM should I set the rev limiter at??? Right now I have a 5400 chip in the tack light & a 5600 chip in the rev limiter. But I can't seem to shift fast enough when I see the light to shift before the rev limiter cuts the motor off!!! {maybe I don't have the reflexes of an 18 years old anymore?}.... THANKS Bill
