Sorry I posted this in a couple places, but I need help with this.

Ihave 370/CC minute RC Engineering/Denso injectors on my 5.3 truck, and a P-1SC Procharger. I have got my Ltrims pretty close to where I want them, slightly negative, close to zero. I pulled one of my plugs to look at it, and it look like I am lean. My 02's show 900's anytime I am in PE or WOT.
I went to for a wideband dyno today, and was refused because my blower makes too much noise so they are afraid it will blow up on their dyno ??!! thats another subject though. It makes the characteristic ATI chattering and rattling at idle and slightly above idle.

How do I fatten up the PE mode? I have the WOT hot and cold PE set at 65%TPS until 3600 rpm's, then at 60% TPS after that on the WOT PE hot and cold tables.

I guess I was wrong in my thinking that if the Ltrims are good, that the PE will be rich enough.

Can someone please enlighten me as to how to fatten up the PE. I have no wideband in town now if they won't do it, so I am on my own.
Thank you very much for any help Sam
