Cats removal , change sct tune ?

[Sammy11]

if i remove my cats , should i get a new tune ?:dontknow:

first i'm gonna try to remove the back 2...

General rule of thumb is to tune anytime you add a new part. May not always be required but you wont be using the full potential of the new mod without a tune.

i dont think a tune will do anything if you remove te back cats alone. there is nothing back there to throw anything off.

if you remove the fronts to you will need a tune or sims, i believe...

 

[FastRam]

I vote yes.

The back 2 will not increase power enough to bother retuning....even removing all 4 doesnt need a tune though tuning may wring out few more horses...

 

[rbabody]

rears no tune
fronts recomend a tune or your check engne light will be on

Sims are alot cheaper than a tune,. you can also make your own for alot cheaper than Sims too. stink knows how to do it with sparkplugs and some other stuff. maybe someone who knows how will join in

No real difference in performance. Made a diffence in the sound though. I tuned mine again anyway and couldn't tell, except it sounded faster

Ask Torrie, or Stink they'll know if that mod needs a retune, but my guess is no.

Tune, can get rid of the popping on decel, if they cut the fuel.
