Did a little more tuning on the pick up

Red line is the old tune that was going a little ricj up top and the blue line is the new tune. Other than changing the fuel around I also added a underdrive crank pulley. These pulls were all through the mufflers.

This is a 347ci LS1 going through a 4L80E, 12 bolt with 3.73's and a 275/50/15 DR on buick riveria steel wheels. Converter was locked.

I added a little more fuel to it right after the 428 pull and it dropped to 422 but I didn't give it time to cool down like I did on the 428 pull. Then I got out of the truck, uncorked it and made a 430 pull again with no cool down.

I'm guessing it would have made 435-440rwhp if I let it cool down again. But I'm not out to set dyno records.. Just want it dialed in.

Hopefully that gets me a little closer to that 11.99 NA timeslip I would like.
