Over boost

I have a 97 F250 with Hybrids and a D66. I have custom tunes from PHP and Minotaur software. I am new to the software so I am starting to slowly make changes. When I get into higher boost numbers (35-38psi) an over boost code is set. I do not have a boost fooler. Do I need the fooler or can I make changes to prevent the code?

The 95-97 trucks aren't as accomodating for tuning changes that allow you to "ignore" boost. Your definition (as well as ours since they're the same) doesn't have any MAP sensor parameters.

If you want to try to run your boost higher than that ( :yikes2: ) you will need a regulator put in the MAP sensor hose.

What do you mean no map sensor parameters? Is that not what the Low Boost Fuel map is for? I don't think you can stop the CEL from coming on with it but it adjusts according to the MAP sensor.

As to fixing the defueling you're stuck using a regulator.

Most of the MAP sensor switches and min/max stuff is in the parameters section, not maps.
