Dan--With a 2 point change, it is difficult to determine if that is the cause for your new found speed.
Was it a back-to-back comparison
When working with engine timing you need to look at "total" advance. A timing light that allows you to dial the advance to bring TDC to zero is best. Most engines see "total" advance above 3000rpm. Too much timing and while the engine may seem more responsive puts you closer to detonation. A higher octane fuel will allow you to run more advance. As suggested a dyno is the only way to really measure the affect of timing on hp and torque. I read somewhere that you can do pretty well setting timing at the drag strip. The idea was, you'd do a run, and then advance the timing a little. Do another run and check your time. Keep advancing the timing until you 1/4 mile time drops off. Then retard the timing back to the previous setting. I have never tried this, but it sounded reasonable when I heard it.
Dan,
When Matt advanced the timing of my car it also meant me running higher octane gas. I see either your car or your sisters at his shop from time to time. Have you ever had him tune them?

Matt did have it for a little while and there was issues trying to tune it properly. The car does not have a tunable ECU yet so there was not much he could do. I do intend on emailing him with what happened to get his opinion.

Dan,
I would not account all the time made up due to the timing change. The track sucked in the AM speedy dry all over and it just sucked. Me, Marc, and Forrest all picked up about 2 secs in the PM race, usually we will pick up or loose tenths not secs. It may have made a small difference but not much.
Why don't you just give yourself credit for driving better in the race because the HP you would gain if any would not be enough to pick up 5 secs.
Like everyone else said the only true way to find out is on a dyno.
