Hopefully this will help someone out...

Like many of you I did not want to lock out the IMRCs, I understood that the difference between being locked out or not locked out would be minimal but since active IMRCs would be slightly better in some circumstances I decided that I wanted to keep them.

Bought harnesses from EOD tech, got the Lund approved instructions and familiarized myself with this diy post and got to work winth fingers crossed that I'd avoid a pesky CEL.

Get everything installed, feel elated that the car runs and rush to get my first log into Lund. Everything looks good on the log and before Lund sends me the first revision P2007 pops it's ugly head. Convince myself that it was possibly a fluke and load the revised tune after clearing the light take the car out for some aggressive driving and so far so good. Next morning on my way to work CEL.

At this point I know that I'm either in for a long and lengthy troubleshooting process, one that I don't have the time or desire for.... OR I lock out the IMRCs and go back to enjoying the car. I chose the later.

Order the MMR lockouts and let Lund know that I'm going to need an adjustment made to the tune. I like the MMR lockouts, but the fact that they give no instructions for them and charge you a fortune for idk $3 worth of materials I wouldn't blame anyone who chose to save the money and chose to zip tie instead.

Once the lockouts arrived I needed some help in figuring out how to hook everything up, found this video and got to work.

Now here is the best part, the install is SO MUCH CLEANER NOW. If I saw a clear example of a 2018 manifold swap with active IMRCs vs one with locked out IMRCs I would have went this route from the get go. Everything just looks so much better. Learn from my mistake, save yourself the headache, save your engine bay and go Lockouts from the start.



PS Car pulls like a totally different animal now thanks to the manifold upgrade, totally worth the money and effort even with the extra headache involved of having to redo install due to CEL.

I was wondering the same thing. I am auto with 3.15 gears and don't want to kill my low end since I drive 100 miles round trip to work Mon-Thurs. I see you have 3.55 gears.
Yes Sir. I drive a little over 80 miles round trip mostly highway. The instant kick is not there as when the f150 was in but it gets up to speed quickly. I did lose some mpg's this past weekend but was driving her hard/wot a few times.

the rear of the intake looks so small with the actuators gone.

So I just ordered a JLT intake. Should I have ordered one for 15-17 or the 18? The 18 I take looks like it sticks out further at the TB opening.

My 15-17 JLT cold air intake fits perfectly with the Stock TB & 18 manifold.

Good cause that's what I ordered. Seems like there is some difference with the size of the 18' JLT because a lot of the reviews are saying they don't fit under the stock hood properly. Maybe that's due to the lower hood of the 18?

After first trying the plug and play route and it not working.
I then hardwired them inplace and it still did not work.

So i locked them out and didnt look back.

I got tired of pulling the intake and redoing wiring connections its just not worth the hassle.

it will fit. the '18 intake at the opening sticks up at a steep angle compared to your stock one.

Any suggestions guy's? I'm planning on doing the install and just ordered the Lund NGauge with custom tune because I'm planning on keeping the IMRC's functional. Lund is telling me I must upgrade to LU47 Injectors. Is this true?
