Fixing up a tune on a 598cubic inch Big Block Chev.
WOT timing was locked at 31degrees from 2000 thru to 8000rpm and was idling at 12:1 AFR. Which is obscenely rich and fouling plugs when I got the car.
Previously tuned by a very well known shop.
Now it drives nicely, has an actual timing curve and uses nearly half the fuel to idle and drive around at low load.
Back to Detailing By Terry to make it pretty and functional.
