Alright Moxie!

Actually, my motor would be about perfect with 27# injectors, both mathematically and out on the strip. My plugs will show good color at reasonable fuel pressure settings at the big end of the track, but cruising around in the pits or around town and its pig-rich. The 30# are just a tad too much but the 24# aren't enough. I can't say enough though that EVERY CAR IS DIFFERENT. For example, the guy that just won the Spring Break Shootout in Trophy Stock was running 11.50's at 118MPH on 24# injectors. He has to crank the fuel pressure up to 55psi to do it though. Could he run the same times on 30# injectors? You bet. It may take him a little while to figure out the tune, but he should be able to do it and at a more reasonable fuel pressure setting.

CobraR, your times are great for no more than you've done to the car. But I'll still hold that your ET and MPH don't match as well as they could. Now it could be due to traction (although that usually shows up as higher MPH), shifting, headwinds or any of another million factors, but it could also be due to fuel starvation. Look at your time slip and see what's happening after the 1/8th mile marker. If the car's falling off on the top end, I'd look at fuel or air...or both. Not trying to piss ya off, just trying to be helpful.
