Guys I changed plugs and new diverter valve….

Air to fuel ratio goes from 14 to high 15 while this is occurring I can’t find anything obvious.



This has to be boost creep/ boost leak somewhere right???!

yeah I've gone through and checked everything i can I'm building a boost leak detector today i just got back from AZ to CO last night but after more research I'm also wondering if maybe its a wastegate issue like something is malfunctioning and opening at the wrong time which and shutting not sure. just trying to get it to stay at the top this forum has a lot of smart people in it so hopefully the right eyes get on it.

literally nothing i just drove 2000 miles in total and i have zero codes i drove 900 miles to AZ there i changed the plugs checked all connections and then went to ford and bought a new Diverter and hooked it up still nothing.

I noticed it about a month ago but its was very minor and honestly only really felt by me and about a week before my trip my wife noticed it but i couldn't find anything on it and it was on a off.

during my drive down Wednesday i was bad similar to the video i posted. watched alot of youtube looked through here and was assuming it might be plugs, BOV, or loose connection.

i haven't really seen anything on the forums that fits this issue since i don't have any codes.

mods.
Accessport V3 93 oct with TCM
COBB front mount IC
Oil Catch Can
muffler and res delete, x-pipe install
.
so nothing serious mechanically messed with besides maybe tune but this is pre and post tune. so im thinking that is out of the question.

So you had the issue before you put the 93 tune on and after as well, hmmm?
Does it do it when cruising at a certain rpm? What if you downshift to the next lower gear but keep the same speed?
What gap did you put on plugs?
