Tuning for catless downpipes???

[svt54]

Ok, guys. So, I got a tune from Torrie at Unleashed last fall for my Flex and I love it. Here is the issue. I have a CAT going bad, and a buddy of mine is trading in his SHO. He is selling me his catless pipes for $150. I can't pass the deal up. I emailed Torrie about revising the tune for the catless pipes, and he responded that he can't turn off the rear O2 sensors. I really don't wanna stare at a CEL light forever.

First, is there a MIL eliminator for our cars? Second, can anyone recommend a good tuner who DOES turn off the rear O2 sensors, preferably using my SCT tuner? I don't have any sort of emission testing in my area, so that is not an issue. I really wish I had known this was an issue for Torrie before I went with him.

MIL eliminators will not work

Sounds like a bummer!! Not sure if AJPTurbo is taking new customers but I highly recommend him. Just PM him, he is very reasonably priced, his hp/tq numbers are wicked high, and he is a local guy on the forums. Ton of support and he uses SCT.


Brew City Boost is another SCT tuning company you can try. Lots of good reviews from guys who are tuned by them. Plus they have the first non-meth SHO that ran an 11 in the 1/4... minus weight such as seats.

I personally have been tuned by LMS, Unleashed, and AJPTurbo.

Good luck!!!

Going though the same thing here only with LMS catted dp.

Is this some new law or did somebody get in trouble for turning off the rear O2s?!

Unleashed sells ONLY uncatted DP's! And Torrie won't turn off the O2s? Makes no sense..

I know LMS will. Not sure what complications ChrisJ is having? I have catted SW DPs, and LMS turned the rear O2s off for me because I was having P0430/P0440 codes. Call or Email LMS and talk to Anthony.... they will fix it for you.

It's maybe because he does not sell them any longer.IDK. Z

I'm sure he does not sell them anymore. Z

Torrie tuned my car so I dont have a LMS tune atm.

SCT got hit by the EPA and turned over a ton of their tuners who were turning off the rear 02's for people. Thus tuners are not turning them off anymore to keep from getting fined even if it is a strictly only offroad tune. MLS uses a hypertech tuner so they havent been hit with the SCT backstab.

I do have a mycal though sitting on a shelf in my mancave. Just have to send it back and get it setup for my car. Wish I could just buy the tune and move it over since its unlocked.

So SCT dealers did get in trouble for the turning off the rear O2s..... interesting.......

A few did that SCT turned over. Blame their bullydog crap and the big coal rolling diesels that think its cool to "roll coal" in peoples faces. Big fines so make sure and not mention to much who will do what or they will all stop. I have to turn off my CEL pretty much daily. I emailed torrie for over a week before buying it letting him know what I had and was told it wasn't gonna be an issue. Well it was and when I asked about it I got legal mumbo jumbo nonstop.

Sucks for honest-minded modders, but I can see why they won't do it anymore.

Cant blame them tbh. Dont mean I have to like it LOL

I hate this CEL so much

[hawkeye93]

I have LMS catted downpipes, which do throw a CEL.  All 3 of my tuners (Torrie, LMS & Brew City Boost) disabled the rear O2s when I asked (a few months ago).

December 5, 2016 for me and the answer was no. Like I said cant blame him but it sucks as I will have to go to another tuner now as I cant handle the cel.

its easy
you need a new tuner
