idles fine but dies when accelerated

[chasmosis1]

I am attaching a log file & tune in hopes that someone here can help me. I have transplanted a 5.3 into an 87 K10 truck. the truck has a small cam that i will adjust for as soon as I can get it to run and it is using the original 700R4. The fuel pump has been replaced and is holding around 54-56 lbs. There is no vacuum leaks that I can find. The truck fires right up and will idle fine, but it wants to die if it accelerates past about 1000 rpm's. Thanks for any assistance.James 041818.hptIdle but dies on acceleration.hpl

Just a guess, but it looks like your leaned out all the way to nothing.

Any clue as to why? I have good fuel pressure.

Was it a known running engine? If not, did you check the Injectors physically, and the injector info in the tune?
I don't know much about HP Tuner yet, but that's what I would be leaning towards.

go to Engine>torque managment>abuse set RPM limit to 7999 rpm and speed limit to 0 mph let us know if it helps

Seems like it has o2 sensor problems too, they stay for a long time at 0mv or very close to it.

It's not going to want to run very well in closed loop if they are like that.

Thanks for the replies. Turned out that the O2 sensors were wrong and the injector data was wrong as well. I corrected those two issues and was able to continue on with tuning it.
