Map graph help My setup is
Iron block ly6, l92 heads. CR 11.5:1 quickfuel 750 carb. 50/50 mix of 93 & 110 fuel. When we dyno'd the engine we got the best results with the timing set at 30*
I drove it around on street & I got these numbers
850rpm idle @ 20.5psia (been told that's way to high, but multiple days comes up with this reading)
My average cruising speed is 40mph & it's at 2,300rpm in third gear with a 13.0 psia & my stall is at 5,500rpm
I know each car is different, just hoping you guys can point me in the right direction to get it close

Can't really help on the MAP question since mine's locked from 1000-8000 with a 7600rev limit...still tuning.
So, whats the rest of the combo and what it dyno at ? Any time slips ?

I have a few tunes in the file to try next outing (Told the Boss I wanted off the Saturday May24th). This isn't a cruiser, so not looking for MPG 
I can only wish you luck at this point.

check your MSD settings, you might have the wrong map sensor selected in the drop down menu. you should be selecting 1 bar. I want to help you but not untill the psia readings make sense
