ok so i either suck at life or everyones tryin to fist me. my exhaust is stock back to the Y pipe. i cut out a 5 inch piece behind the right cat and gutted it cause it was clogged and now i have a flex pipe there (they dont work, i know that now) and now my exhaust leaks and rattles and my service engine light is on. im gonna do LTs and texas speed ORX in Jan. can someone EXPLAIN the difference and the difficulties between tuning the sensors out and using sims???

tune them out..

difference is with a tune they remove all those codes from your pcm and since your going with LT's you can also get EGR and Air codes tuned off aswell as other things.

the 02 sims are just like dummy's that go plugged in to the rear 02 sensor connectors.

thank you. everyone kept telling me which one to get and which one was better and it was a 50/50 split. but no one actually explained the difference. but going by that its pretty obvious the tune is better.

Yes, just tune then you can also tune other stuff out if you want...sims would just be wasting your money.

Yep... if you are going to get a tune anyway why pi$$ more money away.
