Allen is sending me a tune w the cat delete. Do I need to buy the o2 simulators? Or will the new tune just take care of it and leave them in?

You will NOT need sims. That's the purpose of turning the codes off.

Damn, that sounds more like a fuel starvation problem. I'd check the pressure and if it's fine check the volume of fuel flow. Do you have the 255 or 340 lph pump? If you can't rev out more than 4k you've got real problems somewhere undoubtedly outside the tune, unless you got a bad PCM. An incorrect installation of the Walbro fuel pump can cause more bad than good. If the connection between the pump and steel line comes loose, leaks or the connector hose ruptures the truck will still run but not have enough fuel to perform.

fuel system remains unchanged from the prior setup. walbro 225, 43 lb inj. never had a fuel prob before. will check pressures.
