Fuel problems. Help I have just installed a Procharger and in the process of tuning it. I am running lean at around 65% throttle. I am reading this with a wideband, which reads 14.3-14.9 cruising. However, as soon as I start to roll in it it stays at this reading. I am afraid to deck it before I get this done.
I tried using the injector offset map but it does not help out at this throttle. I have also tried using the injector flow but, I am having no luck with that. I have done a search and this is what I have read to add fuel. Help me, please.
I have also posted this on the Tuning section, but I though maybe someone had some ideas.

Re: Fuel problems. Help Parish8 had a thought a while back about lowering the open loop threshold down from 85% to something lower as he was seeing a few pounds of boost at 50% throttle. I'm not sure if he ever did, but it would basically throw the truck into WOT mode at whatever throttle position you set it at.
Look in the Engine section, fuel tab, look in the "WOT HOT" button for the table.
