OK so I have a friend who installed cam phaser limiters on his 04 F150 5.4.
It bucks now and will not accelerate, and has a very bad loss of power, so they called me to see if I could figure out the problem. Also, the idle is rough, but not super nasty..
So I found that the limiters limit the retard to 20* max camshaft retard.
So I opened up the tune and changed a few things and got it running. pretty smooth but but my time got cut short and I had to leave, but when I left it was running pretty smooth but had very little power above 3Kish RPM.
I figured maybe someone here could take a look at it and see if I missed something.
All they want it for it to run smooth, have decent power, and idle smooth. Regular 87 octane, no racing or anything like that..
Enclosed are the stock tune and the modified tune. Thanks guys!
