I been running my 27 Advantage Victory with my own mefi tune Areomotive fuel system etc.. . I`m running a 454 Mag MPI with a procharger putting out 5psi of boost. For the last 3 years have been running the motor with the stock timing curve with no issues or detonation knocks on my scan pro . Does anyone have experience with timing a supercharged engine that that can chime in . I have the ability to adjust advance with my Mefi tuning software .

Can I change the advance for some performance gains or just leave as is ??

I do not have any experience with boosted timing curves, so I'd be hesitant to make any suggestions.

I have tuned my MEFI and the timing tables were the last thing I played with. Very little was noticed with timing changes unless there was too little in the mid range, mid to 3/4 throttle acceleration zone, then if there was insufficient timing the motor was lazy and sluggish getting on plane.

If you've had no problems I'd probably not fix what ain't broken.

Here is the timing table from my Procharged 555 if that helps any...
