After making a few pulls on the dyno, Ramsey found that our coupe was happiest with 14 degrees of timing with the 125 shot. The air/fuel ratio was a safe 12.0-12.5, and it made 344 rwhp and 361 lb-ft of torque. Without the juice, it made 257 rwhp and 277 lb-ft. So the 125 shot produced over 86 rwhp and 84 lb-ft of torque, and even caused a little tire spin on the dyno (arrow).
