Bryan nice run man.
It could be your pump.I don't know your set-up.What afr's were you seeing up top?
I started noticing my afr's rising at high rpm's the other day in the cooler weather and even more yesterday [coolest day in a while].The afr's have been good in the warmer weather.So I hooked up a mechanical fuel gauge and realized my single in tank Walbro 255 can't keep up the pressure at high rpm's.I'm going with an in tank Bosch 044 and I have to get it in before the 16th so I can run.

I could swear he has the inline 255 and stocker in the tank.
I bet your not. On your past scans, justin has your afr rock steady all the way through the run. If it did start to lean out, it would have to lean out pretty high to cause you to sputter IMO.

Mine gets up to 12.5:1 and does not sputter. I need to do something about that before the 16th also.
Russ - Why not try a voltage booster on your 255?

I am runnin the inline 255 but thats not the problem. The problem is that Ive lowered the back of the truck 2'' shackles removed the overload spring and then runnin 28'' tires has messed with the gas gauge and it wasnt picking up it showed I had a 1/4 tank. lucky **** I am it went lean like 2 or 3 secs before the end of the 1/4 mile I am terrible at not remembering to keep an eye on my gauges Ive got to remember to glance over at them or its gonna cost me another motor I dont even want to go there again.
