Re: ANOTHER PROBLEM :(
It takes more spark to jump the gap in higher compression, and at high rpms the stock coil probably can't recharge itself with enough power to keep up. MSD 6A would solve that problem. Make sure your ignition system is always perfect.

Re: ANOTHER PROBLEM :(
Drop the gap on the plugs down to .032, but first i would fix your fueling issue.
since your running an FMU without atleast a booster pump, or a walboro, that would be another one of your problems.

Re: ANOTHER PROBLEM :(
WHat does the wideband say?
Plugs need to be gapped lower but you have to go with what the wideband says.
I Have my plugs gapped at stock n/a specs and mine runs fine.
I Had to gap em lower once but then I found out I had a vac leak in the im that was only pressent during boot, well boost leak.
Also my friend leo.. with his boosted k8 and fmu. Yeah he blew his engine for the third time.

Re: ANOTHER PROBLEM :(
i now run my 1 step colder ngk iridium plugs at stock bpt gap. I had lessened the gap yrs ago to prevent the spark blow out from too much boost but since then I have tuned many things.
