ok a buddy has a stock gvr4 and it blowing a bit of black smoke under boost,
so its running rich and it has a 1g ecu in it and the stock gvr4 mafs,
is that why its running rich?
does it need the 1g mafs to compensate since it has the 1g ecu?
the boost leak test is good, timing (both) plugs everything is good
