I got a set of Stainless LT's with random tech highflow cats, with anSLP LM2. I also have a Lingefelter CAI installed. If all that was installed. Would i need a tune to not damage my engine?? With WOT or whatever.

I have been running with my catless Lt's, and Corsa. Check engine light has been on for a while. No big problems. You will need a tune. Just might be able to drive it for a little while before you get one though.

you'll be fine. You're not maximizing possible gains w/out the tune, but you will damage nothing.

My car with catless LTs and stock everything else had a 12.0/1 AFR all the way from 3500+ before tuning. I would think with a CAI and exhaust your AFR may be a little higher, but still well within the safe zone.

You will be rich, but safe.
Not like carbed cars where it leans out with more air. MAF will adjust to the air, thinking the car is under a heavier load and add fuel....
