I had to buy the catch can the mechanic said he wouldn't change out the mass air flow because of all the oil that was on there until I put one one. I put a jlt on the drivers side.

How do you get oil on the MAF? The line from the valve cover is well past the MAF. Even if there was enough oil getting into the intake tube and it ran down to the MAF it would be on the bottom of the tube and should not affect the MAF. Do you run an oiled air filter?
If indeed you are getting enough oil getting in there to mess up the MAF you may have larger problems. May want to measure the compression and do a leak down test to make sure the engine is not hurt from all your high speed runs.
What mods have you done to get 17 PSI boost?

No did not run any oil on the ari filter. Dont have a clue how it got on there just that the mechanic told me that there was oil all over it and it was messing with it by what his computer was telling him. The dealership was checking the whole car over cause they couldnt figure out after they changed all that how it would still be misfiring.
here are my mods
127mm jlt carbon intake
Ford cobra jet mono blade TB
NGK TR6 spark plugs
Kooks 1 7/8 headers with high flow cats
2.396 upper pulley, and lund tune
catch cans on both sides
Dyno numbers are 732rwhp and 711 torque

do you have the older version of the intake or did you get the updated version? also what kind of tune are running? timing?
What are you talking about old version and updated version????
running a lund tune and dont have know what the timming is

Tucker, the JLT guy, released an updated version of the intake because of some issues people were having when the air gets forced thru at high speed. I know its a lund tune, should have asked if it was aggressive or mild. At this point I would have the engine checked for the compression like someone mentioned and then recheck all your mods, make sure your plugs are gapped correctly. Contact JLT about the intake.
everything is all check on mods. i contacted jlt and the update is only for a heat shield and thats it do not know if it is a aggressive or mild tune.
Ok. well good luck. And I would contact Lund and at least get the basic parameters of your tune. As an owner it's always good to know what tune you are running for any future reference. You can adjust yourself via handheld should conditions change ( such as bringing the global timing down when its really cold out)
I'm wondering why there is so much oil being forced out of the valve cover port into the intake? How is the oil getting blown back out towards the air filter? Is there a restriction in the PCV valve or the line from it to the blower? Is there a way to measure crankcase pressure? I go along with the other guys on a cylinder pressure and leak down test. You may have some ring issues.
sounds like a ring issue
question: reguarding the bolded section, how would one perform a 5th gear top speed run? this is the first i have heard of this. i just drive a lowly GT but i have kept the throttle pinned in 5th for much longer than 8s (i would guess somewhere between 15-20 seconds) to see if the car would even pull itself at redline....was this just asking for issues? why is there no mention of this in my manual?
i am very sure this is a stupid question, but would like for someone more knowlegeable to explain this limitation to me.

I believe you just answered this yourself...."your lowly GT" does not have this feature. Specific to just the '13+ GT500. And yes, you are asking for issues running yours 15-20 sec on over-rev.
you are forgetting that you are comparing a GT which is made to rev at 7K and just beyond. The top speed you can achieve with that car stock is what, 160 ish? So in fifth for you, the speed increases differently and you are trying to approach top speed without being at complete redline. The GT500 is a different motor with the power its pushing its not as rev happy. Secondly it is capable of hitting 200mph, so in fifth gear its not near 7K rpm's at it reaches that speed. Thus the "over-rev" feature will not kick in. The feature is really meant more for as you are blasting through the gears drag racing or road racing where you would reach the 7K redline. For me I usually shift around 6700 at most to be safe, but mostly around 6K
If your mechanic has not already checked, make sure the pcv system on the passenger side is not obstucted, ie pcv valve stuck closed, hose pinched or collapsed. You might be able to pull the valve cover, there should be a baffle to prevent raw oil from entering the vent lines. Good luck.
Finally got it fixed
well was running high flow cats on the car and took them off and put off road x pipe on have more flow so it lower my boost from 18 down to 16 and now it is not doing the random misfire
