Dyno tuned 305 TBI on the gas
The colors of the runs got swapped between me making both graphs. Blue is the same, but red and green are swapped. Go off of the run names in the header.
Red pull was NA before tune/green on afr graph
Blue is NA after tune/
Green is 150 shot/red on afr graph
What is really amazing is how much tq and power it picked up in the power band. In one section it picked up over 75 ftlbs NA

He is not all that far off from my 305. It had headers, stock cam, stock swirl ports, stock intake, stock TBI unit.

Re: Dyno tuned 305 TBI on the gas
Great case for why you need to tune. The original HP/TQ graphs are a mess.
