Default Car harder to start since relocating the MAF after intercooler?

Hi guys. I have a small issue. On my SC setup I relocated the MAF directly after the intercooler When I installed my meth. I did this because I hooke up a seperate IAT sensor down stream from the meth nozzle so I can log my IAT temps to see what the temps drop to when the meth starts to spay. the MAF used to be a few inches before the TB and would start no problem. Now on the first start the car will stall, second attempt it will start. Is this due to the lack of airflow in the sytem? Here are some pics:

Screened maf? If not some turbulance could be messing with it from the ic.

Putting the MAF there is not the best thing.Turbulance from the intercooler will screw with the readings.I would bet the part throttle tuning is off now too.

I would put the MAF back with the MAF temp sensor and spray the Meth inbetween the MAF -TB. Then adjust the tune to compensate timing/air fuel.

I switched from the non-screened 02 to the 01 screened. I figured the screened would get more accurate readings. It's weird sometimes it does it then other times it doesn't.

The Meth kit might be leaking into the inlet pipe too.

HiTempSilicone makes 4 ply 4 inch 45 degree elbows-only thing is the intercooler outlet is kind of oval-do you think an elbow like that is okay for the outlet of the intercoler. I figured the rubber elbow would be the best way to mount the maf then make a new straight pipe with the meth nozzle and IAT sensor. I'm not sure how much boost those elbows can take though.
