    Service engine soon or Malfunction indicator light. If the box is checked that means that that code can turn on the dash check engine light to let you know if there is a problem. People will turn...

    The MAF is failed at 1hz but you failed to let it fail the MAF completely. It can't fail the sensor if you tell it that there is no problem, having the 3 MAF dtc's set to no error reported won't let...

    I've never found the proper data for the marine injectors but maybe it's out there.

    If you are having to whack it with that much fuel to make it run good. My guess is that the injector data is...

    What's your fuel pressure?

    What injectors are installed and is the data correct?

    The idle timing is really high for just a supercharger too.

    You have to redo the MAF airflow curve and the VE table for the change in intake manifold. There is no "change this or that" and bingo it's all done.

    The low end and higher rpm will need a once...

    I'd be checking the harness for problems and the fuse block to make sure it's all good.

    Unless you know a guy or are very savy with a computer, no you likely can't do anything yourself. You can't buy HPT, plug it and just delete the emissions.

    If the engine is stock just like you say it is, fuel pressure is good then yeah the tune should be okay.

    Adding headers won't make the fuel trims go nuts like that. Usually there is another issue...

    Yes, that would need to be turned off as well. There is a camshaft selection spot that you'd change from one to none.
  11. You need to go in and also turn off everything...

    You need to go in and also turn off everything related to the AFM/DoD system otherwise it won't want to run on all 8 cylinders.

    Disabled the master "switch" for the DoD system in the engine side....

    Okay. Then if it's still that lean just at idle you have a vacuum leak or exhaust leaks right at both o2 sensors.

    I'd look into a leak in your cold air intake, throttle body gasket or intake...

    Stock fuel pressure is suppose to 58psi on a LS engine.

    Raise your fuel pressure and see if it stops being so lean.

    Are you trying to log the AEM specific channel or the WB Eq ratio channel (I think that is what it's called).

    AEM has a youtube video showing the channel to log. I'd have to get my tuning laptop...

    Can you provide a data log too?

    Closed loop operating in the tune file anyway is still all active. I've never seen a cat-back or muffler back exhaust make a engine just run lean for no reason.

    Holy cow is that a ton of timing swing at idle, that isn't exactly what I would want all for a smooth-ish idle and to help combat the smell.

    Just took a quick look, they forget to half the IVT...

    From a fuel trim standpoint and not seeing the tune file, the fueling is alright when in closed loop. It has some knock retard once you get above that 3,500-3,700rpm that you can see in the log. It's...

    The drop down menu for automatic to manual does nothing. The base file has to be a manual for it to really be a manual.

    Yeah. Doesn't matter if it's speed density or MAF tuned. The EQ ratio in PE will determine what the requested AFR/Lambda.

    No stall is surely not helping at all. Can't get around that with tuning.

    Without a dyno we are both just guessing here. I wouldn't say you need to spin it a hell of a lot higher, maybe a few hundred rpm give or take.

    If you have a good stall converter for that size...

    The camshaft has to make power there, otherwise you are just wasting your time revving it that high.

    What you hear is how they all are when you have no cats and no resonators.

    If you have good valve springs you could run it to 6,400+. I've seen guys with 4.8's run them close to 7,000rpm.
