2022 Mustang GT Premium Performance Package ESS 120mm
I recently put a G2 supercharger kit on my 2022 GT premium performance package (manual). And I’m having a ton of issues. It’s running very rough and wants to die out.

The entire motor when turned on runs insanely rough and doesn’t not want to stay alive as if there’s a vacuum leak or something else going on. When it idles at 800 it’s very smooth, anything under and it wants to die and throws misfire codes. I’m trying to get a datalog long enough to send back to Lund for revision, but it truly doesn’t want to run.

The belt/tensioner/pulley is causing a big issue. All the steps were followed to a T and double checked. I have a 115mm pulley with the correct belt size. It starts going crazy after the blower pulley, then wants to jump off the alternator ribbed pulley, jumps off the alternator 1 tooth (towards front of car), then goes absolutely crazy between the alternator and crank. Which then causes the tensioner to jump around and sound god awful. What could the issue be? The alternator wasn’t changed and neither were the bolts. All the pulleys are straight and spinning nicely.


I also need help with IMRC lockout tube routing. There are plenty of videos showing the 18+ manifold conversions for 17 and under, also how to install lockouts, but nothing for 2018+ tubing. The line in the back of the manifold originally attached to the brake booster to my knowledge gets capped off. ESS also states to cap it off. But here’s the problem, it runs terrible when capped off. When it’s open and sucking in air and causing a leak, the motor runs much better.

Lot's of things could be happening here.

1- are you sure you have the belt routed correctly?
2- change tuners immediately
3- be certain that your MAF sensor is pointed the right direction. The pocket of the sensor should be facing the passenger side.

Why would you cap a vacuum line that feeds the brake booster?

There is really no reason to get ride of the IMRC system on 2018+ cars. The 2015-2017 intake manifolds had issues with the shaft that controls the flaps, and would break but you aren't gaining anything by deleting them

I don't believe that anything should be getting capped off in the back by the windshield. I didn't anyway with the same blower and year car.

Do you mind showing me the setup you have for your air lines? I can’t find any information on this.

1. The belt is routed correctly, and I even installed a new tensioner to play it safe. But it’s jumping around so much it has to be something crazy.
2. I’m unfortunately 1300 deep into a custom tune by them. Their LRX tuner I bought and am not sure it will work with other providers, as well as the custom tune was pricey. I’m hoping for the best… please give me some good news lol.
3. I did prior, but will double/triple check again when I get home soon.

I wouldn't worry about the tuning part right now

The MAF sensor can only be installed into the MAF tube in one direction, but the tube itself can be installed backwards.

I'm going to bet that you do have the belt routed incorrectly.

I did the same thing on the vacuum line for the BOV. I didn't do anything with lines in the back of the intake manifold at all. Why is it capped? What did you hook the line up to?

This sounds like it's related to how you routed the belt, or the new tensioner you installed possibly.

Other thoughts: You can lock out the IMRC but like others have mentioned you won't get much if anything out of it on a 2022. #2: On a G2 if you're on pump gas I think the smallest pulley they recommend is the 120mm for Gen 3 engines.

Is this the routing that you used? It shouldn't be able to jump around at all.

That’s what I was told as well as what ESS says. But again, Lund said get the smaller 115 pulley.

The IMRC was removed and capped off in the rear. Do you have lockout or no?
