Okay, so I put on LTs, off road h-pipe w/o cat, and flowmaster axle back w/JLT intake and tuned via SCT. Ran it fine for the past month with no issues, been up to Nurburgring and no issues. I was driving it Friday night and noticed when I got on it, I wasn't getting all the power I once knew just a week prior. I'm getting a little greyish/whitish smoke from the tail pipes, and it smells like it's running rich. No codes are coming up, but I know she don't feel right. It's really noticeable when I reach 2-3K. I checked the bolts, and they are all good. The O2 sensors aren't loose, vacuum lines look good, so I am at a loss. Any ideas?? You think me not having catted h-pipes would do this? The only other thing I haven't tried is pulling the plugs which I am about to do here shortly. I am up for anything. Please advise.:shrug:
