good idea,he mentioned about the fuel pump maxing out where that bump was toward the end,i just ordered a 255lph to drop in

maybe he'll read this and chime in..

I don't think that it is the fuel pump maxing out unless it has a cut off switch built in that shuts the engine down so it won't melt when the fuel pressure drops below a certain pound.

It's classic valve float under load. It's happened only once before for us, but I know alot of tuners who get it alot.

There really isnt one crane spring out there that doesnt need machining to before dropping in, and I'm assuming their dual springs. The fact that you couldn't get the keeper out leads me to believe it is weak springs. Give Chris Tillman a call tomorrow, we'd like to get it back up on the dyno when she's ready!
