After I installed the big ass check valve the limp would happen less often but would usually occur at full throttle and high rpm so it makes sense . After adding the 100 octane I ran a gear down and even rode the limiter in 3rd and 4th gears which has been an automatic limp in the past . Could def tell a significant increase in torque as well .
