What's the prognosis? DR.
I put a superchager on a 99 SS camero.
After three runs of tuning it started blowing white / blue smoke.
Vac went from 20 to 15, idle is rough.
So what do you think it is?

The car still has a lot of power.
It also pops through the intake once and while.

I agree with pulling the plugs and doing a leak down to narrow your search.

so I opened the high and low octane table and lowered all cell values by 5. then did the second run (no ping)
then I added 2 back into the High / low tables.
then did third run (very little ping)
I'll pull the plugs and see what they look like

I have no real expierence with these type of superchargers but is there a chance that a seal could go bad in them allowing engine oil into the intake via the supercharger. the popping through the intake sounds like a different problem possibly in the tune

This is while using EFILive and making scan runs.
it is in SD with the MAF disconnected.
