boost issue (posted in wrong thread)
 

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!
