Carbon trap/filter removal - did I do this correct? 2023 M1

[Mach10Maverick]

Today I pulled the carbon trap out of the inlet tube. I reinserted the inlet tube back into the primary intake tube as before. What I removed is basically the size of 2 stacked hockey pucks. Seems to run fine - No tune, everything is stock except the carbon filter removal.

Yep, you did it right.

Perfect

Pulled carbon filter out of 22 GT in the air box. Is there also a carbon trap somewhere? Didn't see between the air box and throttle body. Note, this is not a Mach 1.

That’s the only difference besides the tune from the factory on the 2021 Mach 1. On the GT’s I don’t think it mattered as far as factory ratings, but those might be -10 also. A tune and an intake should put you back to the 2021 spec.

Yeah the GT is minus 10 also. Didn't know if there's a carbon trap as well as a carbon filter in the intake tract, thus my question. Can't tell if people use trap and filter interchangeably or if there are two separate components that need to come out.

Also, run 93, which isn't available in AZ (need to mix from 91 and 100). Catch can on the way as well, which should help maintain octane.

IIRC the carbon trap was a flat panel in the airbox lid on the 22,23 GT and it was in the airtube between the filter and throttle body on the mach 1. They both lost 10 hp with the carbon trap, from 480 to 470 on the mach and from 460 to 450 on the GT. You don't need to get a tune to get the 10 hp back, just remove the trap.

Thinking they added intake airflow restriction without implementation of any ecu changes in tuning to compensate? I’m not too sure that makes sense.

They did make changes, but they are so minute, they don't matter. You can just remove the trap and drive it. But if you want to have it tuned, the fuel trims are a little off, those need to be adjusted to get it perfect.

That’s why I mentioned the tune. There are people on here that think having the factory bolt on the HP wheels make it a different car.

Just my 2 cents, the missing 10hp comes at the top of the RPM range where the air restriction becomes affected by the carbon trap. You'll never feel it. And for daily driving it has no impact. As for tuning after carbon trap removal, the mass air flow sensor should compensate for the slight increase in air flow, so it's not needed.

Only thing you didn't do was box it up and send it to Gavin Newsome.

LMR did a dyno pull on a 2022 with the 10 speed auto locked in two different gears (4th and 6th, IIRC) while running an X pipe and 93 octane. In the higher gear (numerically lower) there was a more noticeable difference down a little lower. The car I'm asking about is a 6 speed manual, with less drive line loss as well.

This was the car you're remembering.

5th gear

7th gear

After 4k the trap becomes a choke, more and more as airflow demand increases with rpm. The difference between it being there, and not, is no different than the change that would take place when driving down from Denver to your new home in Houston. The maf sensor is more than capable of making the needed changes. Just leave the air straightener screen that's directly in front of the maf in place and there's zero risk.

I think I finally figured out the answer to my initial question (carbon trap vs. filter). There's a carbon trap (in the Mach 1 only) and there's a carbon filter (GT only with a little pad on pre-22's replaced with a bigger more restrictive one in 22). So I don't need to look for the circular hockey puck one on the GT (as it's Mach 1 specific). I did see the insert and the issues with making the post MAF diameter bigger so not touching that. Thanks all!!!
