Car runs lean with maf plugged in / perfect when unplugged

[Aesthetics28]

I just installed a vortech v3 unit, with 47# injectors, and a high flowing fuel pump.. I can't figure it out i swapped the maf out still nothing...my air fuel ratio goes to 17-20. I'm not sure what to look for or how to troubleshoot this

Vacuum leak?

are you using a MAFia?

I'll ask this, you uploaded the blower tune?

If using mafia, is it set properly?

 

[Aesthetics28]

Yeah I'm set at 2using mafia

Vortech add on pump? Watch your fuel pressure. Those thin hoses get cut easily. Happened to me.

Yeah I did this is the second tune that's been like this

did the tuner tell you to set the MAfIa @ 2? and did you tell them it is set at 2?

I told them it was set at 2.. They never told me what to set it at

I purchased it from my man Kurtis on the forums whose been also helping my dumbass through this mess haha the only difference between my car and his is that he has cams

It's a tune/mafia issue. With the maf unplugged it goes to default trims and bypasses the tune, hence why it runs fine.

My advice, sell the mafia and get a maf with the range you need for your setup like the HPX or BA5000.

 

[Saleen4971]

Well it doesn't bypass the tune, it just goes to base from the tune.

For some reason I revved the living dog shit out of it and it seemed to stabilize it self but in the process I burnt out my o2 sensor for my afr gauge
