GIAC stage 1 tune - Pinging

[noone]

I'd be a little concerned about a company that acknowledges your new tune is pinging and to come back when its convenient for them (after you've done possibly a few hundred or few thousand k's over xmas). IMO they should have put it back to stock until a suitable time they can resolve the unknown issue.

the ECU should be able to work around many limitations, i'd definitely chuck in a new set of plugs for the $20-40 it will cost you, I'll be changing mine every 10K kms from now on.

if you're game, logging may help.
