I got a 03 whether its on the stock tune or street tune it misses at WOT. The truck doesnt seem to start that hard but runs like #### the first 7 seconds after startup(might be cold related). I am thinking it is either a bad injector or 2 I am not recieving enough fuel or oil. Whats you guys thoughts?

No codes yet but about a month ago I had a IPR code but it went away and hasnt showed up again.

Will a AE get fuel pressure readings?

I was looking at buying a AE anyways.

On edit: changed both fuel filters 100 miles before this post

No it won't. The only way to get fuel pressure is to add a gauge. There is a test port on the filter/regulator housing under the hood. Tap into that. You will need a metric fitting btw. IIRC it's a 12mm x1.5 thread pitch.
