correct, tunes do not change, if there is a change, something mechanically / electronically has changed in the car

have you tried running the stock tune just to see? diablo had me run stock tune and disconnect battery cables and touch the negative and positive cables together for 10 seconds.

I haven't tried that. Would it be okay to run the stock tune at this point for a little bit to try that? Even though I have catless headers and jlt intake. I don't want to cause another problem.

It will barely run with the stock tune and the JLT alone. Put the OEM CAI back on if youre trying the stock tune.

i had that problem with my intune. it needed updated to the latest firmware.

What exactly was the problem you were having?

Update:So I checked the plug on cylinder 8 and everything is fine. So I put it back. The misfire code went away. I still have the same problem with the idle. But now I have two other codes p0100 and p0104 which indicates a problem with the MAF sensor circuit.Which wasn't touched. Its weird. I'll probably take it to a shop. I don't what else I can do. All else fails I'll have to remove those damn headers and see if ford can help.

the tuner wasnt updated so it would only load a base can tune. if i adjusted any parameters it wouldnt run. i posted this in july or august. and when it would run on the can tune it would throw a code. once i updated everything was fine.

find a local speed shop that can dyno tune.

The fact that you keep having different codes pop up and go away is very strange. Good that the #8 plug looks alright and isn't oil fouled.

Have you tried returning the car to the stock tune, deleting the Lund tune from the tuner, make sure the tuner is up to date, reload the Lund tune back on the tuner and reflash the car?

If not I'd try that next. Good luck!

Before you return to stock clear all codes and do a KAM reset.

i have seen people load the incorrect tune on their car before

happens all the time

return to stock, make sure your up to date and follow these instructions

good chance you have a canned tune on the car and not your lund tune

Lund told me it could be short somewhere since I keep getting circuit codes. Expect for the misfire code which is gone now. I'll recheck the o2 harness and wires. I'll recheck the tune as well. But I put the stock intake and stock tune on and still had the same problem.

Sorry to hear man, atleast you know it's not the tune. But tracking down an electrical issue sucks. Good luck I hope you find the issue and get it fixed soon!
