I have a Direct Port 80 shot. My tuner told me he was gonna retard my timing as far as he could on my MSD digital 6 ignition. I think its like 6 degrees. I thought that sounded like too much, because i heard timing should go back 2 degrees per 50 hp. With an 80 shot, shouldn't i just need to retard 3-4? Are we talking about drastic differences in performance?

Thanks,
Jon

 

3-4 degrees should be ok, he is probably taking it to 6 to be safe. No it won't be a drastic change in performance. hope you have a good fuel pump

 

Jeff's right, 6 degrees is too much. Do 4, if your car lags, go to 3. But then again, don't listen to me. I was running stock timing and just busted up my motor.
