The mopar was at 35.5. I know all motors are different. I think I will take mine to the local dyno shop and see if I can get it dialed in.
That's a fantastic gain with just 2* of timing. But where in the power band was the gain? If it was at peak horse power, that 20 hp and 30 ftlb torque is not going to really help you. Those gains would be beneficial on the track at 6800 rpm trap speeds, but for street driving, most of us don't wind our engines to redline. I would be excited if those gains were in a useful range of your engines power/torque band, (2500-4500rpm's). I agree, If you can take your car to a trusted local dyno shop and get your car dialed in on the dyno under load, that's the best way.
