Pull out all of the spark plugs & wires. Remove the fuel pump relay. Hold the throttle wide open while you are cranking the engine over. You should hear each revolution...
Crank it for 5 revolutions without letting off the key. Watch the gauge while it is cranking. It should jump up in 2 or 3 large jumps and then level off. It helps to have somebody else turning the ignition key for you.

Post up your results.

 

The 20's surly are not helping with the et and 60ft times.. Drop down to a smaller rim/tire combo, I bet you shave time off, rite there..

 

This heat is really bad for your power adder. You will most likely pick up almost .5 in some cool weather and yes please try some light wheel/tire combo.

 

Ok, I am ashamed to say I never got around to checking my compression. I don't think there is a problem though because when I did it I never pulled all the plugs, and never opened the throttle at all. I will get to it, but I was more interested in going to the track tonight. I decided to disable my water/meth as Tim and Roger were having such good luck without any. Anyways I decided to just run the AFR at 11.7, and turn the timing up until it would ping, or not improve speed/time. Well, long story short, I made 3 runs, and my last was 12.49 @ 109 with a 1.88 60' and 24 degrees of timing, and no knock retard. I bumped it up another degree, and missed the last run by the time my truck cooled down. I know that's a lot of timing, but what the hell.
