MAP sensor

Is there an aftermarket MAP sensor for these trucks, kinda like putting a 3 Bar sensor on a turbo car?

None that I am aware of... I can say that the way your powerstroke handles the MAF sensor readings and the way that a turbo gasoline car handle the MAF are completely different. There would be nothing to gain by altering the MAF ( to my knowledge ). With that said, I have actually installed a block off plate on my intake and voided the MAF readings from the PCM all together.

Only reason I did this is because I was getting a code for the MAF reading and didn't feel like properly correcting it; so I deleted it.

I've wondered this also, need to talk to a tuner to see if they can change the settings in the PCM. IDK if it would help tuning or not but it would be nice for data logging from the cts.

What's the issue? Are y'all regulating/fooling the map for defueling reasons. And finding the cts or whatever reads fooled pressure?

My torque pro will read backwards numbers when the MAP reads 33.something psi

The MAP sensor is 3 bar so it will only read correctly to 29 psi at sea level and the ebp sensor pegs at 37 psi. If a tuner could allow for a 5 bar map and ebp tuning could be further refined for big vgts.

Sorry.. My mind has been wrapped around a way to be able to delete the MAF sensor inside of tuning for the last couple days

it's all good Jay, I'm just curious, I think it could allow for more precise tuning and such so that's why I asked
