Just wondering if anybody can lead me in the right direction. I'm hp tuned and I have a Catless dp. I have no codes and my car runs good. My only concern is that my led on my Onstar is always red and my car sounds like an srt4 when I slow down or downshift. Sometimes I get loud pops.

 

thats normal for the most part. your tuner could have left it a bit rich or something tho. but the pops happen to me too especially when i downshift in lower rpms.

 

Yeah the pops are normal. I sometimes get a pretty loud pop shifting into second at low rpms.

 

Watch any catless LNF video and you will see that pops are normal. I love them. It's a good cereal as well.

The onstar thing I cannot help with.

 

my onstar is red sometimes and green sometimes, its not a problem, I believe there was a thread about it a while ago. As for the pops, I think they are normal on a catless car although I'm catted.

 

My car does it. I believe cats burn off excess fuel that does get burned in the combustion chamber, when you are Catless it let's the raw fuel out causing a pop. Just a theory I could be wrong

 

What bothers me is when I talked to Onstar they told me I had an antenea issue and I had a emissions code. How do I have a code with no check engine light?

 

Perfectly normal and I like the way it sounds

 

mine does it so bad the car will turn off :-(

 

i love the pops haha.

and for the red light im pretty sure you just press the onstar buttom or something and ask them to check it.

 

Uh that's gotta be a misfire, big difference from what's being discussed.

 

so are you guys meaning pops as in a lawnmower backfireing because i just put my zzp catless dp on today and drove around the block and it did it like atleast 5 times lol.
