Almost feels like Im not getting full ignition until full boost.. almost feels like a studder.. How can you tell when a transistor goes bad? or a CAS goes bad? or even my MAF?? or fuel pump?? but i figured when fuel pumps and mafs go, they just go and dont work at all...

check engine light came on 3 times out of no where, and had the same reaction to the car as fuel cut does, although i was just at cruising speeds twice, and idling another.. The light went away before i was able to pull up link and check out what it was. Happened 3 times in the past month. When my first MAF went bad, it did a similar reaction, but it didnt keep working after, i had to change it. Its a 3" gm maf with MAFT zeroed out and dsmlink for tuning.

Plugs are 7s and are gapped to 30..

Compression on a warm engine, not full operating temp, was 138 across.
I read that service limit was 122. I know 138 is not where i want it, as 150, 160 is, but cant see it being my problem..
