Hi all, I have an NM Power Module on its way to me today. I wanted to get some baseline readings on my 2019 MCS, so using an OBD II reader and the OBD Fusion app, I took the car for a spin, hammered on it for a bit and am seeing peaks of 13 psi. What could be going on? Either my car is already tuned or the app is garbage, right? Anything I may be missing? Thanks!P

 

Isn't that normal? Pretty sure stock boost on our 2021 JCW is 15-16

 

Normal. :-)

With the NM module you'll probably see ~15. Doesn't sound like much but it makes a noticeable difference on the butt-dyno.

 

Cool! For some reason, I read that stock boost was only 8 psi, but that must have been wrong.

Now if only the thing would get here! UPS had it on the truck for delivery here in AZ yesterday and now it's in TX.

 

So did you get it installed yet? How do you like it? I have one for my 21 MCS but have not had time to put it in yet.
And are you running on 91 or the 100 setting?

 

I did. It's a lot of fun! The install is super easy. I didn't remove the airbox as the instructions call for. Not sure why you'd need to. The low setting was a noticeable increase in boost, but I had to see what high is all about. The highest octane I can get is 91, so I filled up with that and a bottle of Lucas octane booster. I'm getting more boost, upwards of 19 psi, and it's a riot. No real need to downshift when passing. High is a little less smooth in its operation. Could be because I'm running lower octane than called for, but there is some hesitation from time to time. Once I burn through this tank, I may switch back to low.
