Yes with the carter strip pump I was experiencing some nosing over at the top end. When it would nose over it would run 10.9,s. When it didn't nose over, still felt like it was pulling, 10.8,s. Figured I would up grade to stop the nose overs at the top end figuring I could get Consistant 10,8,s. Well ended up getting consistant 10.47/10.50,s

Wow, wasn't expecting that, sometimes you can be starving for fuel and you Wont even know it. And yes Pump change only, nothing else. Thought I was just having some occasional fuel starvation nose overs.
