Anyone here gut the cats or run an off road pipe without a tune? I'm just wondering if the car will go into limp home mode. I'm planning on gutting the cats on mine but don't have a tuner yet to turn the sensors off.

 

I would not risk it....You will get an MIL light for sure and it very well may go into limp mode depending on how you drive it

 

I just installed the MAK o/r x-pipe a couple hundred miles ago. I had the C&L CAI, Magnaflow catbacks and a Diablosport Predator 93 tune for the C&L installed.

Dyno'd it last week and the A/F ratio was completely fine at 13 through the rpms.

I have not gotten any warning lights or anything.

 

Off road pipes are the same as removing the cats from the bassani x-pipe correct. From those who have installed those, I have heard that no tune in required.

 

No Tune Required....

 

While it's not required, I would still be hestitant to let it run without a tune

 

the car will run lean..DYNO fact

 

Maybe the Diablo tune was running rich for me, then...
