2013 Ecoboost F-150 keeps dropping boost

[Japeatr]

I am trying to hunt down an issue with my truck dropping boost. it will spike to about 20psi then pull boost back to ~10 no matter the settings.

i have checked the BOV and IC clamps. but wondering if we are missing something in the tune that keeps pulling it back.

any help would be appreciated!

Thanks

thanks let me give it a shot!

Much better, I didn?t get a chance yet to grab a log or a full WOT pull but can already feel less hesitation than before

Ill grab a log later today

Didn?t get a chance to log it but it is so much better. Truck pulls super hard, just need to verify the computer is reading 20psi and fix the 1-2 and 3-4 shift under wot and im set!

Big thanks kel83 for the assistance!!

Also got my forscan cable today, any recommendations for niftyness would be cool too

The thing that stands out to me, is your Wastegate Canister Spring Preload. It is set at 1.47 psi and most of the stock ones I have seen are around 4.75 psi. Have you changed the wastegates on this vehicle (if so, the 1.47 psi may be ok)?

On a side note, I do not think it's your issue, but your EOI Clip is pretty high at 665 degrees. This allows for injector opening well into the compression stroke which seems off to me.

No good octan? High temp?

I cant seem to find Torque airflow limit and torque max protection source?! What am I missing?

[kel83]

Ok, if you add channel in scanner, use filter limit and source, after add all what you see

[Japeatr]

Let me know what you think? Seems like truck isnt pushing more than 12-15psi, but is holding it better!

[kel83]

your limit

Ahah! You the man! Is this for cats or manifold protection? I guess what im asking is how high to raise it?

[Japeatr]

Disregard last question, I just needed to read and determine rate of change

[Japeatr]

Upped the temperature limits in the higher load cells above 4k rpm by ~75F, and the surrounding cells in ~3k by 15-25F. Going to start here and see how it runs.

Also put in a 160F tstat as my fans were working a$$ off trying to keep desired ECT
