I would think you would need to explain the pro of even wanting to do this?

Or how you would do this.

They make a device to do this easily. Ive just never understood why

Pros and cons for deleting the direct injection on 18 and up mustangs

You don't even need to delete it. If you really don't want the DI just disable it in the tune, simple as that.

Now IMO that's kinda pointless, you lose all the benefits that come with DI and gain absolutely 0 performance.

Lethal sells a block-off kit. It would be kind of nice to be able to remove the valve cover without removing the intake manifold and other associated hardware. Not having to buy a $40 high pressure line every time you pull the passenger valve cover would be nice as well. Other than that, I can't imagine a good reason.

DI is the best innovation for ICE since variable timing.

Keep thinking that.

It's the first thing to disable when realize 465 HP was just a romantic vision and need to downgrade to Ecoboost power haha.

It's an easy 150 HP loss if can even make it happen.

2017 made 435 with 11:1 2018 is 460 with 12:1 the point is worth 4%

not looking for any gains thanks for the info

Peak HP rarely tells the whole story. Most of the benefits of DI come in handy elsewhere in the power curve. The torque gain at low RPM and in octane limited situations is pretty nice.

Have there been failures related to DI on the mp/di coyotes? That config was a big part of the buying decision for me. Pretty high tech for American muscle.

I haven't heard of any. Since the system works in tandem with the port injection it's not terribly high strung. One pump on the passenger side exhaust cam runs both banks.

Ok so what's the reasoning to wanting to do it and looking for pro/cons?

Probably wants a quiet engine.

Probably wants a quiet engine.

That's fair, it is pretty loud. But at that point, why spend a premium on a 2018+ only to disable one of the better features of the new engine...might as well get a 2017.

So the cons are more money spent, less power, worse fuel economy for pros of a slightly quieter engine.

Either way, it's easy to do in a tune...just have a reputable tuner make changes to when the DI comes in.
