This should allow me to raise my shift points to 7000 RPM or more if I desire. Wondering if anyone has figured out how to improve the shift times. Also had the shop doing the pulley upgrade perform a compression test on all 6 cylinders. My engine has a little over 100K miles. Any way the results were excellent considering the mileage. Four cylinder had a compression of 170psi, one had 160psi and one was at 180psi.
