how to trick the emission computers?
just got an email notification today that my tags are due this month and that i need to get my truck emissioned also. it's a 05 so i expected that this year would be the year to get my first emissions tested. i know all they will do is plug into my truck and see what the truck computer tells them.
a couple years ago i put pacesetter lts and y-pipe on. i added high flow cats to that combination but of course left out the rear O2 sensors. i got the truck tuned shortly afterwards but they didn't delete those rear O2 sensors. they have since sold their tuning software. i know there use to be sims i could plug into the sensors but they are pretty much impossible to get now. will the spark plug defoulers route work well enough to trick the emissions computers?

I have a similar setup with Magnaflow cats and my 02's are right in the stream and I do not get a check engine light...So for sure in AZ the defoulers will work..or check eBay for 02 sims used...or get a mailorder tune.........
-But I say just put the rear 02's back in as is.....

I can't just plop the o2 sensors back in bc the y pipe didn't have the ports for them. So I just unclipped them from the connector near the frame. And I don't want to have to pay to get a mail order tune after I've already had it tuned.
