this one. was running rich and my buddy and I tried to fix it.  
Now it won’t idle or start. cranks and runs for a bit @ 450-500 rpm but then we try to add gas and dies.  
Will check spark plugs and probably grabbing another Z32 MAF tmrw.

thanks

Hi Cadence. Are you running a KA-T or SR20DET?  
What is your injector size?

Also: IN/OUT settings?

SR20DET. 550cc injectors.

In/out I have at 10/50 right now. Previous owner told me he had it at 20/30. I don’t think anything wrong with maf…but copped a spare just in case.  
Got it idling proper but anything past 2k is poop
