It feels like i lost a lot of power in the low end, i can't hear my blower anymore, and its ****ing annoying.
Should this have happened with a simple res delete? needless to say, the cat is going back on

No.

note i can't hear my blower because it's so loud, not because it isn't operating correctly

3800's always sound like crap. You just made it worse.

What is your total exhaust set up? Unless you have open downpipe your exhaust shouldnt ever be louder than the supercharger. Was the resonator replaced with 2.25" piping(if you have factory exhaust)? Changing the exhaust diameter too much can have a negative effect on velocity and flow.

You say cat is going back on...? Is it off currently? If so wwithout a tune that gets rid of the codes you might be running rich..
I deleted me resenator and it didn't make it too much louder

woops, meant the resonator is going back on. im currently running lean, as i installed SD headers and a 3.4 pulley while deleting the resonator all at the same time.. Still waiting for my PCM to be shipped to me. Stock cat back, except for the straight pipe in place of the stock resonator.

Usually would run rich without codes deleted and no cat....shouldnt sound too bad....an aftermarket exhaust added to the straight pipe is when most consider installing a res/glasspack..

maybe with your 3.4 pulley your getting kr, which pulls timing and cause the sluggish feeling... idk.

what kind of timing should i see, im scanning with Torque.
I did a few KR tests and it showed no detonations
and i think with the overkill pcm if i do have any misc. KR that it will take care of that and the lean problems.

Why would you think the resonator delete is the problem when you say it was all installed at the same time? Also are you running a true wideband to know that you are lean? As long as the same pipe diameter was used on your stock exhaust then it isnt the problem nor anything else you've put on.Originally Posted by drewhanover

I ran headers, no cat, no res into stock muffs. quiet as a bird

^^^This. If you are running a 3.4 with a stock tune (because your pcm hasnt arrived)you most likely have kr and its killing your power.

im guessing that's what is happening. honestly when i first put the pulley on it smelled really lean, and now it smells rich. hopefully the problem goes away when i put the new pcm on. I'm having problems getting torque to read my KR, it just always says zero, so that's pretty much useless
