Hey, so I’m just trying to figure out my next step. Here’s the issue;
So what I’ve done to my 5.3 is change the manifold and TB to a ported 6.2 version, Carven muffler dumped down before the rear end, Stillen air ram, Red Rock cold air intake, and a Pulsar LT module. Noticed it’s idling kinda rough (needle jumping and twitching), hiccuping while I’m driving, and a couple times actually shut off on me in traffic!!!! Now, I do have a pair of long tubes that I want to get installed as soon as I can get it dyno tuned… but I’m just not ready to fork out the 2,500 for that yet. Could this all be that I need to get the air/fuel adjusted? I can’t find a vacuum leak. Would the dealer do it ya think??I know I’ll have to pull the Pulsar out before. The rough idling happened first when I swapped the TB and manifold, but now that I installed the Pulsar LT it’s very noticeable and it did cut out in traffic once already and cut out at cold start this morning. Any info is appreciated. !!!!
