GEN 2 Loss of power

[c_phillips02]

2017 raptor is stock besides catch can.
Driving 60+ and roll into the throttle truck will lose power and fall on its face. Truck will build boost but has no power. Floor it and still no power but notice boost is down at wot when it’s doing this. Then other times it will drive just fine and have plenty of power. Seems to be worse when the truck is warmed up. No check engine light or codes. Doesn’t stutter or shake like a misfire. Replaced plugs, air filter and oil level is good. In attached video I am giving it a good amount of throttle to just hold speed on a flat road before I floor it. Anybody have a similar issue?

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?

Boost leak?

Boost leak?

I wouldn’t think a boost leak since it drives fine 50% of the time with full boost.

What fuel do you typically use? Cats plugged?

93. Wouldn’t plugged cats throw a code and drive bad all the time?

Your IAT2 (downstream) temperature is high, the PCM is pulling timing to protect itself from detention.
What's your outside temperature?

I’m in central Texas and today was around 95*. Would it pull that much timing to make it feel like it loses 50% power? I have forscan also so I can check to see what it’s showing.

All these i initailly thought cracked end tank on his IC. Hook up a scanner and see if your shutters are opening. Or you can remote start and warch them cycle.

Also could be the boost recirculating valve stuck open.

They do cycle after remote starting it. Maybe the one in front of the intercooler is closing while driving and killing my IAT. I’ll hook up the scanner and watch the shutters and IAT when it acts up.
