    It's stumbling and bogging because it's lean....... Unless you have a boost reference regulator, 42lb injectors will never be big enough for that much airflow on that displacement - just one of the reasons why the MAF is all screwed up... Another observation just looking at the log - why does your map max at 103kpa while looking at your MAF hz, your obviously running at least up into the 180's kpa range - Is the right map in this thing - never mind looked at the tune - obviously correct map was never installed? You also need to log more after fixing the current problems...

    Just some quick observations.

    Magnassun kits, out of the box, use the stock MAP.

    I don't think it was part of a kit , I think he grabbed somethin from here and there , I swear it was like trying to unbake a cake

    Ohhhh, so it's one of "THOSE" kits That explains the injectors.... Hope everything was installed correctly since it appears the owner did the install himself - seems like that has bit me more times than anything

    You can go as big as ID1000's as long as you use the double stoic half flow rate trick - this will be the best route without having to full scale the tune... It looks like you have a mechanical fuel pressure regulator via the tune - if you do - you can figure out how to possibly plumb in a boost reference regulator - this would allow you to run smaller injectors, but still wouldn't go much smaller than ID850's...

    Guess the better questions are - Do you have a mechanical regulator? Which magnuson blower setup do you have - heartbeat?

    You'll also want to see if you can't install a 3 bar map - may require different pigtail connector - both decently priced though GM dealer...

    This one? It should have come with injectors.... And if memory serves you either have a regulator built into the filter or it's fixed fuel pressure via built into the sender in the tank...

    So it's got a different TB and everything then? AND he installed the factory SS injectors into it - I assume he purchased it used and is making it work then... OK at least we've got more info now

    Still a little confused with the blower - the one pictured looks like the old cable style TB - possibly 3 bolt setup? Can't see the pic that great... Has the TB been changed to a different size?

    SO, I guess the best question is what all has been done exactly? Sorry to come off like an ass here or any previously Just trying to get some info for everyone...
