GEN 2 Loss of power

Malfunctioning sensor ? Fans not coming on or are fried and overheating?

I’m going to pull the shutter blades and see if that fixes my problem. I live in central Texas so it’s hot most of the year.

Removed shutter blades. Intake temps are lower but still doing it.

Truck is pulling timing bad. Watch the spark knock in the video. Truck is backing the throttle down to 50% when WOT. Have zero misfires and can’t hear any pinging. Fresh plugs, air filter and run 93 octane. Could I be getting false knock?

I hear a blowoff valve or a boost leak at the end.

It has a VTA BOV adapter. I took it off to make sure it wasn’t the problem but no change so I put it back on.

Why do you need a bov adaptor?

I bet you have a boost leak and the truck is pulling time and fuel because its not getting the air it wants vs throttle angle etc.

I don’t need it. It is just for sound.

The ECU is seeing knock according to the spark knock #’s. I do not hear any knocking or pinging. When it runs good the spark knock is showing 0 to -3 and has plenty of power. I’m leaning towards it seeing false knock or a knock sensor is bad now.
