Is your tuner a piggyback that won't affect the factory warranty?

Thanks for the reply. I'll be in touch. Would like to discuss a custom shift schedule that eliminates the skip ship, holds the gears like the tow haul mode without the hang up, but will up short shift sooner, like around 2200-2500 rpm under normal throttle. Would also want the engine tune to be...

I didn't notice any performance gain on 93 except that the fuel mileage was about 2-3mpg better which didn't offset the price difference. For what I use my truck for, I have no interest in a tune excpet maybe to make the tranny not skip gears. And before anyone posts a reply that I should run it...

I'm going to take a serious look at the Canyon Denali as well unless it's priced crazy high.

Easy guys! A little background regarding my experience with 91-93 octane. My truck is bone stock. I'm in sales and drive it about 500 miles a week, mostly on the highway. I noticed during around town driving that under light load from 2000 to 3000 rpm that it would ping a little running 87...

Yep.

Yep. That's it. It seems to be better in cooler weather and definitely less on 87 octane gas which is strange.

It's getting 23-24 on the highway which is where it spends 95% of it's life. I'm running 91-93 octane. No oil test. No codes. I purchased the factory engine cover and installed it since the cover was deleted after 2020. It does run good and it may be just the way that it is. However, I can't...

I've tried to record the sound but it doesn't come through on the recording.

Thanks. Just annoying to have a truck this nice that perfotms so well and have it sound like a worn out VW Jetta TDI.

Thanks!

Appreciate the response but have to disagree. I've owned several I4 direct injected turbo vehicles from the 2.0 Ford Escape, which was very powerful and quiet as a mouse, to BMWs and none of them made an engine noise like this. At moderate acceleration around 3000 RPM it truly sounds like I'm...

My issue is not vibration. It is sound. The engine, only at normal acceleration around 3000 RPM sounds like a VW TDI but quieter. Very light throttle or hard acceleration has no noise. The engine is very smooth.

Mine only does it under normal acceleration. I tried to get it sitting still and it doesn't make the noise.

I'm going to take it to the second dealer and ssk them to take a ridr with me. I'll post the results.

I've been through two dealers and had the TSB done by both at the direction of Ford Customer Service. Neither helped with the low speed shudder. I picked up the highway vibration after the first TSB was performed and now can't get rid of it. The second desler performed the TSB with no...

It was standard with the purchase from the dealer. Once the standard warranty expires, as long as I have documented maintenance done per the Ford maintenance schedule, the entire powertrain is warranted for as long as I own the truck and any repairs are covered and done by any ASE certified shop...

I have the lifetime powertrain warranty so not concerned on that front. Just wanted to see if anyone else has had the same issue in case I get the same "normal characteristics of vehicle" BS from Ford that I got about my low speed shudder and highway vibration that I still deal with daily. Can't...

Everyone, I have a diesel like rattle from the engine during normal acceleration at around 3000 rpm. When accelerating on very light throttle or hard acceleration there is no noise which tells me it's not a valve or rotating assembly issue. It seems to be getting worse. My 21 FX4 is 8 months old...

Ford is supposedly elevating my issue to an engineer butnoyhing has happened yet. I had the tsb done with no result other than creating a vibration at 80 mph. I shimmed my center bearing down 5/16" and that reduced the shudder but did nothing for the high speed vibration. My next step is a one...
