not 4 but .4 (half a MPH)...fresh pump no tuning. Now I have a true baseline to go off of. Haven't posted anything since I want to get more data. My HEI coil took a dump on me on that trip so I don't know what really is going on.
BTW nothing was in the intake no grate or loader. It was WFO...
Now I need to put a loader in and see what happens. After, I replace the coil, I'll go and take another GPS reading with the loader.
