I had been running <1/4 tank (habit, and never a problem with the stock fuel pump and bucket).
The new fuel pump does not have a bucket at the pick-up point in the fuel tank like the stock pump. Ergo, fuel sloshes around, and it gets worse with each pass (less fuel).
Needless to say, I'm running a full tank of gas this Sunday. 
But I am hitting the track!  And the roll cage is going in on Monday for the Atlanta Camaro5 race at Commerce next Friday!

Good traction, best so far is 11.029 @ 125.97 with a 1.704.
Density Altitude is over 2000, so it's a bit warm for records, but I'm happy so far. Now I can tweak the rest of the tune.

I wish I would have known you had an aftermarket pump with no bucket. I've seen this a lot in the GM trucks and it is why I kept the bucket in my turbo truck.
Glad you got it figured out!
