I dont recall too many V4 maps having read me files, most of them were posted here back in the day with instructions. It's been so long.

OP you might want to look into a rev 2.5 upgrade, it has many benefits including extra fueling capacity and better tuning.
Why would you need to? A good number of us push 20+ psi through the RBs with no issues on the stock plugs, myself included.

The point is like I said before, if plugs coils injectors or vanos don't fix it, not much you can do, short of running cobb with no misfire detection. Maybe a valve cleaning but I doubt it.
Yeah I deff agree. I am on stock plugs pushing 17-17.5 and no issues at all. I doubt his problem is plug related.
