Default New PB! 6.39@107

Only ran twice tonight...still having issues with the knock sensors going off. Still spraying meth and I put 10gallons of e85 in the tank before going to the track and it still wants to pull timing. Pulled 5-6 degrees (max allowed is 6) most of the first run and trapped 103. Plugs looked fine so I went out on a limb and set the max retard to 2 degrees and trapped 107...plugs still look good afterward so im pretty sure something is just banging around giving me issues. This track is known to trap a few mph slower than normal.

Best run I left on the 2step at 4000...I think the sweet spot might be around 3600-3800, but still managed to launch on 18psi after a burnout and got mitch to clean off my front tires Thanks mitch!

It still pulled 2 degrees most of the run (total timing around 13 degrees). Injectors were around 102-105% most of the time, so im glad I have meth to spray on top, and this is at a 0.80 lambda. I may try a higher base pressure (70psi perhaps) to extend these a little further. Curious to see how the denso pumps like the higher pressure... I also clearly need to get stiffer rear shocks...might try to fab something up for that this weekend too...

0.040 from 4,000 to 8,000

I wonder if having the tailgate on made it more bouncy than usual...that is another 50lbs hanging on the end.

These types of converters like to be flashed not stretched. You will find low 1.4 to high 1.3 is the threshold for these 4x4 trucks. After that awful things began to happen..

I watched a video of the first run I made in slow motion. I spun all 4 through first gear and the front tires were definitely dancing toe in the whole time. Pretty sketchy
