hi folks,

I have a comptech supercharger, when my car was tuned at 9 psi it was tuned with a test pipe and headers. Now I decided to put back my stock cat and stock headers, (can't stand the smell and the black stain on my bumper) my question is do you guys think that I need to retune? or is it safe to leave it alone. Thanks for the inputs!!!

 

Yes, you need to have it tuned again.

 

Afr wont change much! So its safe to drive. But u can clean up the map.

 

Probably you'll run richer now. So you will be safe. If you want you can retune to see if you can get more power out of it.
