I did a little research and you are right about the LT1 stock rev limit. My car was untouched when I bought it and I consistently rev to 6200+ with out a problem. I have all the work done below, but the PCM has not been touched yet (waiting on my headers).. So can anyone explain that?

I have hooked up a digital tach to confirm that it is spinning that hi. I had a post going awhile back about this one, but no official conclusion was met. My car stock was running 13.6's consistently down the 1/4 mile. Now, I'm implying something here, but I'm not gonna say it. I'll wait for someone else to do the honors...

Anyone?
