    How long does obd system take to be available? Ive driven for 65 miles now over about 5-6 day period when i get off work. Cant seem to get it to clear up. I had the battery disconnected on it for a few days last week

    Right now i have the stock tune file in. Catless downpipes, i used to see the check engine light on for them but not recently. So i guess its still trying to figure it out. Unless its better for me to reinstall my 3bar and flash my tune and restart the obd learning

    If you have no cats, you're gonna have a problem getting it inspected. Otherwise, what you show is normal, when you have no cats ;)

    As far as I know, when a tuner "tunes out" the cat monitor, the cat monitor will never go to complete, but it also doesn't light the check engine light and throw a code.

    With the tune loaded, you won't get a code and a check engine light. But that monitor will NEVER say "Complete".

    Place that did my engine work is in an emission county and they have a whole computer thing that plugs in for obd inspection. I never seen it before as where i live is no emission and you just get a sticker and the redneck dude says i like your tires and gives you a sticker. I guess ill go back to him lol

    Why did you take the tune out to begin with?

    I was having an issue with light throttle rpm pulsing. I usually run VTA for the blow offs and at light throttle it was just psh psh psh psh psh psh and i never heard it do it before. No boost issue this time on my log because it wouldnt spit air over and over unless it was light throttle. So i reverted back to stock and clamped my hoses back on and you could still feel it, i checked the wastegate hoses and cleaned the boost control valve thing and it went away for a bit but ended up coming back yesterday. So i ordered a new boost control valve thing but im also looking at the throttle adjustment bolt up top as it was from my old engine and i adjusted it before and im not sure if its causing the issue when i barely touch the pedal or hold it cruising.
    So thats why i went back to stock tune
    Sorry just been a long stressful week, at work and....here lol

    Theoretically, it could be that throttle stop adjustment.

    You know how they should be from factory? I can run it out till the rpm stops moving or i can run it in to the rpm starts to move. Or the other way around. Its nice the car has it as it helped keep the idle up when it wouldnt idle blown up but now it probably needs back to a better position
