    15-17 f150 roush phase 1 stock file needed

    anyone have a known stock read on one of these? installing a new longblock for a customer and wanted to make sure the tune was unmodified,currently has a vmp tune on it from previous owner and we would like to just start him with the factory phase 1 roush tune. im kind of surprised they run the pe lambda at .85 until 4000 rpms before they richen it up i would have expected it to be alot richer throughout.

    Edit , ok I’m kind of stumped so I was reviewing a stock n/a file and the phase 1-2 files for these 15-17 trucks that have been posted on here and it looks like the wot lamda is the same for n/a and boosted, is that right or are the phase 1-2 roush tunes posted incorrect on here.

    I've got 2 supercharged tunes that I think are real. One is a Whipple and the other is from a tuner I will not name.

    The Whipple runs WOT at .82 the other runs it at .77.

    I believe these to be real tunes due to the mapped point and distance tables. They get the same cam positions but use different mapped points to do it.
