i had no codes for catless dp's but after 50miles or less it will pop up. So yes you will get a check engine light soon

I will take it back and let them know.

The shaking in the cabin was less noticeable once the car was warmed up.... But it was still there.


No one answered the following.

Should there be a check engine light because I have gone catless? I HAVE NOT set auto clear on my JB4 yet... I thought there would be a code.

Could the reason it is not boosting well be because the DPs are not done up tight enough?

Btw how much are new o2 sensors
