I put the lbz mouthpiece on and also an lbz k&n cold air kit on my lly and not it doesnt run right. it boggs down sometimes but then other times it runs better than ever. I dont know whats going on with it. I have taken it to the dealership and they rescaled the MAF with the lbz tables and it did get a little better but still not right. i have also cleaned the MAF sensor several times to make sure that wasnt my issue.
Anybody out there have this problem and can help?
Thanks
