Default Blow Thru Setup, Help! Ptuning anyone!

Hey guys, i just had my Maf sensor welded after the BOV close to the throttle bottle on that charge pipe, my tuner claims its to close to the BOV and causing it to stall everytime i press the clutch in... my question is, Is this backwards? is the maf supposed to be where the BOV is and the BOV where the MAF is? or should i just move the MAF further down closer to the Throttle body. *my intake pipe is deleted, filter directly on turbo* also does the MAF have to be on a 2.75" piece of pipe or is the 2.5" fine?

*dont comment on the welding please, its not done yet or coated, just need an answer ASAP*

Mines is just a lil Bit further I think. I think just gotta tune it better or you might have a faulty tb or vss (it's the sensor right by that lil green **** looking thing in your vacuum line. But I think it's tuning.

could it be because the maf isnt going straight down in the pipe and i had it welded on the side so its sideways in there?

but i thought one of the points of a blow thru was to keep it from wanting to stall..

When you run such big injectors and modded setups.. You can not idle the car so lean.. 14.7 will give you a pretty ____ty idle.. Tell him to richen it up in to low 13s high 12's and i bet you it idles perfect! mine idles at 800-900 but i idle 13.1..

try it ;)
