MPG loss with Cobb intercooler

[Venice Raptor]

I have the FP tune on my raptor. I just installed a Cobb intercooler and dropped almost 2 miles per gallon. (It went from 16 to 14). Does something need to be reset.. what am I missing? I assumed my mileage would get better from all that I've read on this forum.

I wonder if thebair charge temp has dropped now so the ecu enriched the mixture a bit


Can you unhook the battery and see if it will start relearning? I am not sure if you can, just asking.


As far as firdt thing i mentioned, cooler air requires more fuel to be at stoichametric (not sure if i spelled that right) so it would use more fuel to stay at whatever the ecu is set to run at. A leaner setting is usually higher temp and a richer fuel mixture is usually cooler and doesnt preignite (knock)

I am stock with a blow off valve and I get 14.9. Maybe you have the same issue as I do, we drive like assholes.

The right foot has a mind of it's own.

Prove me wrong.

I just reset the truck by disconnecting the battery I'll see if that does the trick.

It's likely the removal of the active grill shutters

The Cobb intercooler did not require the front active shutters to be removed only the rear "floppy" ones Which were attached to the factory intercooler. The Cobb installation was quite simple actually.

Boost leak would be another potential cause.
