Went to the dyno this morning....

How about stock lines? Were they upgraded? Some say it isnt nessary and some say it is. Look for obstruction and clogged lines filters. It could have a stock pump on it which may not be enough. If the power stops at 6k why go to 7k? I wouldnt be waiting for the shift light to come up.. Unless your going through the traps.

The fuel lines from the tank are all 1/2" then out of the pump they are 3/8". There is a Holley adjustable regulator on it with two lines running to the carb. The filter is brand new.

I usually don't rev it past 5500, now that I know where the power drops, I definitely have no need to go much higher than that. I'll get a new chip for the light so it comes on sooner.
