GEN 2 Loss of power, under heavy accelerating

[xrocket21]

update.

So in addition to checking the oil levels and the air filter, I did remove the tune all together. I did three wide open throttle pulls through all the gears past seventh gear with no check engine light now.

Tomorrow I will do the same but over 50 miles to go to work one way and I will do 5 to 8 wide open throttle pulls to see if I can replicate a check engine light and to see if the codes are different if I do get a light.

It does feel like a tame animal though without no tune LOL

It's always such a bummer going back to stock.

I feel like these trucks have SO many parameters and sensors, if anything is just a little off, it doesnt like it.

It may or may not help but at this point you should try cleaning your MAP sensors. MAF sensor cleaner works well and can be found at Walmart.

I agree... I have a video of some loud ticking noise, which is rather concerning. The noise is not because of the aftermarket intercooler install.

Allegedly Fords and particularly this Raptor, ticks a lot lol. But mine is louder than it was before I removed the damn tune.

Not necessarily ford, but direct injection (DI) cars in general. The injectors are at super high pressure and it is just loud.

Here is my video...

I find this a little absurdly loud

ya, thats loud

that’s not normal and sounds like a very ominous failure or soon to be failure.

YEP.

I hope they can fix this by 24th. I have a trip to ATL. Going to make arrangements to drop it off today or tmo.

Cheers Gents.

Watching this thread with interest. I don't have the loud ticking sound but have been experiencing a sudden loss of power under load (either feels like it stalled for a second or it hesitates to accelerate. Yesterday it felt like the turbos had quit completely) - though not really heavy load. Truck has 5k miles on it and dealer currently has it and thinks it is the MAP sensor - replacement going in tomorrow.
