M30 bogging down

[ThatOneEuroE30]

So since i rebuilt my M30 its bogs down when your at light throttle and eventually die if you dont feed it more fuel with more throttle. It never did this before the rebuild and all my electronics are the same. I did however put in a 284 degree cam. I'm wondering if the stock engine management cant handle to higher lift cam at the lower throttle inputs? Maybe a chip and bigger injectors will fix this?

What are your AFR readings when it bogs?

What are your AFR readings when it bogs?

Unfortunately I don't have a wide band.. Something I need to get. I dont have an 02 sensor at all but I didnt think that could cause it to bog like that and not really have any other idling issues its not acting like its running rich or anything and I have no issues beside the bogging down.

What's your fuel pressure? How big is your fuel line?

Fuel pressure is good. Don't have an exact number at the moment but i tested previously and it was good. Running the stock fuel system.

Problem still exist and I realized the whistle is not air cleaner but coming from the motor and is an air leak. I can feel air from around the dizzy and cyl 1 exhaust manifold. see latest post on my build thread post #842
