Hahahaha, I think I found my boost leak: ![http://c4.ac-images.myspacecdn.com/images02/39/l_2ae47f090cbd48588be6ea8334b5838f.jpg](http://c4.ac-images.myspacecdn.com/images02/39/l_2ae47f090cbd48588be6ea8334b5838f.jpg) Bypassed the IC ghetto style for now since I have a FMIC setup to go on anyway I didn’t want to fix this POS. Idles a billion times better now, test drive soon. -TJ ---

The biggest advantage to a blow-through setup is the ease of limping home in the event of pressure-side failure. ---

I’ll be going blow-through w/ a GM MAF once I start putting the mods on (and a nice FMIC). I just wanted to get it running well “stock” so I know I have a solid starting point. Granted at this point every problem I had would have been fixed by putting in the aftermarket shit (cam timing off, I have HKS 264/272 to go in so I would have fixed that then - blown-out IC would have been replaced by FMIC) but I didn’t want to put the gigantic pile of parts I’ve accumulated and have it still run shitty and have NO idea where to start tracking it down. -TJ ---

But you seem to be doing your part to make the car run properly and not be a stereotypical DSM owner. Rock on. ---

comp numbers def look good. i think service limit is in the low 130s or high 120s and jjji think the service manual says 173 for perfect compression so your golden. a boost/vac leak is def a possible cause of your high idle as well [Previous page](https://forums.speedlife.net/t/4g63t-compression-numbers/199881.md?page=1)
