RB25 Won't idle with MAF hooked up

[MATTs14]

Ok guys i got my RB25 running and it doesnt want to idle when the MAF is hooked up. I am using the RB25 MAF and I'm running blow through. We got the fuel pressure set correctly and all the bugs worked out.

When i unplug the MAF it idles beautifully and sounds great but when i plug it up i constantly have to blip the throttle to keep it running.

I assume its the MAF but just making sure its not something else. Thanks

I know you arent dumb, but is the MAF facing the right direction? And where is it placed?

[MATTs14]

Its in the cold side of the intercooler piping and its faced the correct way. Its coming right out of a 90 coupler so i guess that could be affecting it. I'm really not sure.

Could anything i mentioned be a part of it?

Big vacuum leak

The maf has to be on the longest straightest peice and NOT after a bend for it to work properly.

I'd say you also need some pressure testing to do.

I'm new to the whole blow through setup so can it be on the hot side or does it have to be on the cold side?? And it idles great with it unplugged so i dont really think its a vacuum leak.

Well my car had a horrible vacuum leak and the car wud idle rgeat with the MAF unplugged, the minute I plugged it in, bam, car starts to lope and die.
