problems with gm maft install

[mygsx2120]

I just finished installing the blowthrough setup and now my car barely runs. The lights are coming on in the translator box so I know it is working. I searced and found out sometimes they are not just plug and play. I richened things up at idle and got it to run, but it stumbles bad and will barely go over 3,000 rpms. The weird thing is sometimes it runs smoother than others. I was driving up and down my street just to feel things out, and sometimes it will feel smooth and then sometimes it runs really rough. I will keep playing with it, but I thought someone may be able to help me from experience. Thanks in advance

What injectors you using?

did you set the maft for your injectors? did u set the right size of the gm mass on the maft?

check that. i had the same problem yesterday, and today i fixed it.

Check your settings on the maft once more to make sure they're correct.

I am still on stock injectors. The auxillary is set to 0 and the base knob is set to 2. I read that was what to use for stock injectors. It is a 3" inch mas so I have all the dipswitches on off. Still need to do a boost leak test, but I figured if it was leaking it would be rough all the time, not just most of the time.
