Try this next time. Lower your rear tire pressure to 25 lbs and make a pass, then try 20 lbs, don't go much lower with street tires. You need to get as much rubber to the ground as possible and still have a good rolling tire. If you have someone go with you make sure you have them line you up in the sticky not in the bald spot. Street tires will pull the HTC right off the track.
Old drag racer's school of thumb, (1/4 mile) for every 10th of a second you take off in your sixty's you go faster, so you can take another 10th off on the top end.
Don't use 87 oct if you are going to the track! Your computer can adjust to your fuel and reduce your timing to keep your engine from knocking. Use the highest octane you can get (not race fuel!) With 93 or 91 octane, use pure gas if it's in your area, you will see a gain in HP and reduced trap times from that alone.
Hope this helps.
