Engine Rev Limiter at 3K

[Longshot270]

You can check and see what it is set at by going to [Power Programming]>Pick whichever tune you are experiencing this problem in>[Yes] when it asks for custom options> Go straight to [Upload Previous Settings] down at the bottom. Check the WOT shifts and compare to your rev limiter. Another thing you might want to check is WOT fuel, that should be around 1.3-1.4. Then just hit menu when your done until you get to the home screen.

Thanks for the tips, ill check that out tomorrow and see what it says.

Please don't confuse my explanation, the truck isnt hitting a Rev limiter thats the effect of what its doing but it only does it for a second then power returns and it goes to Red Line.

How many miles? Possible clutch slip in the tranny?

The truck only has 37K on it 370034 to be exact.

Id think if the trans was slipping i would see it pulling the boat even more and when in Tow mode and the boat hooked up i can red line it with no problems. Though i don't like doing that as its a lot of unneeded strain on my drive train.

I think the P-code is giving the reason for your problem. My advice is to try replacing the fuel filter. P0148 means at least one bank is severely lean at WOT, which is pretty much what your symptom could be caused by.

This is what i saw different
WOT is at 1.3
Shift points at WOT are 5300
Red Line is set to 5600
Tire size i bought new tires not to long ago and there slightly bigger i think.
Stock was 265/65/18 read as 2442mm in the programmer
NEW 285/65/18

Code P0148 Fuel Delivery Error

Does this help at all?

I didnt change any setting but when i backed out it caused the programmer to reload the tune. I hope this is normal and it doesn't cause more issues.


When i put the truck in Tow mode i dont have this issue and thats a Richer fuel ratio. Could it be Bill needs to add more Fuel for the 2800 to 3500 Rev range?
