HI  Everyone. I have a 3B in my UrQ and it ran great for quite a while. 
Recently  
its not running well at all. Car starts right up and idles, but VERY rich  
and a 
good amount of exhaust smoke at idle (from being so rich). Driving  along 
its 
just OK but as soon as I hit boost, its like turning off the  key. It pops 
and 
sputters and damn near dies until I let off the gas, then  it comes back 
again. 
At idle, if I go WOT instantly, it acts similarly,  pops..sputters etc 
until I 
let off, then it goes back to idle.  


Things Ive tried: New ECU, no change. New MFTS, no change.  Checked, double 
checked and triple checked all my powers and grounds to  the ECU and they 
are 
good. Up next is MAF, but not sure how to check  it.

Any other things Im missing? Thanks for any tips!
