As the title says, If I change out the stock DP with the AMS catless one's will the check engine light come on?
And will I be able to drive the car without a tune without risking damage to the engine?
Ordered a 2013 and stocking up parts will try to wait so there is a good tune out there for it before I tune it.

any catless dp will throw a code/cel. you can clear it with a cobb ap, but it will come back. you can drive the car without a tune, but if you're going to mod it with hardware it only makes sense to get it tuned as well. you can run a canned tune and cobb will zap the o2 code so you don't have the cel. joe graham did that for me on their v3.6 canned map before i got a custom tune.

I have AMS DP's and I have never got a CEL. I do have a Cobb AP, but I never had to clear anything because it never popped up.

Does anybody know if there is 2 O2 sensor / DP or 1 ? On the pic's I have seen AMS DP looks to have only 1 slot but others have 2 ?!
