Hey I was wondering if anyone could help me out. I recently had a motor swap, now the car will not run for poo. The car has a comp 224/236 w114 lsa, AFR 190 heads, P1sc(3.4" pulley), 42.5 bosch /lucas injectors, PCM for less just did the tune and car the car just dumps fuel at idle with the mass air plugged in, but if I unplug it the car seems to run well. Good idle and all. Plug it in no idle, surging like WHOA. There are no vacuum leaks that I can find.
Do you think moving the Maf to the presurized side would help?
Any help is welcome Thank you.

 

My setup is very similiar to yours, except I have a turbo instead of a blower. I would definitely move the MAF to the pressure side. My car runs a little rich on cold starts, but idles fine once it warms up. Good Luck.

 

I had this same problem too until I moved the maf to the pressure side. It Idles smoothly now with no problems.

Here's a pic of where my maf is (scroll half way down the page):
I have pics and a description of how I did it.
