Ok. So i have an 06 sc with zzp cai, 3.1 and 42s. I recently got tuned and have had nothing but issues but i don't know if a retune will fix my problem. My boost goes from about 20 psi on the first pull to 15 the second. i also have a significant drop in hp and the first pull whp is somewhere around 180 if that. Intercooler pump is checked and working great. I'm worried I may have a clogged cat. I live in PA so im not sure i wanna go catless because I dont have many friends that are mechanics and don;t know if they would risk it just to pass me. I dont want to drop money on new headers, dp, and exhaust if this issue is just gonna persist. please help me so i can stop the embarrassing dyno days!!!!!!

Thanks for your input everyone!

 

I think you have a posting in the wrong section problem you should try posting in the correct section such as the problems and service section

could be a clogged cat then the pcm sees an over boost and cuts or it it and we only have 1 header not 2 headers

 

i apologize mr. belevedere. i did not mean to offend you with either mistake.

 

lol you did not offend me but this is the performance section not my car is broke section

go get your cat checked

 

looks like im gonna have to. just didnt feel like paying someone to do it. haha. and thats why i posted here. im having a my performance is broken issue haha

 

still belongs here Problems/Service/Maintenance - Cobalt SS Network

get a piece of straight pipe to replace the cat or take off the down pipe and hammer a metal rod through the cat to break it up and it will come out in small pieces

 

ok. ill post under that
