The sled originally came with 9's (and that is what the shop Manual specs) but I noticed the new SDI's run 8's.
I'm chewing plugs like crazy.
Should I try the 8's?
Yes, going to 8s was recommended to me by Dunfords when I had my '04 & it was fouling plugs. Also, make sure your MPEM has the latest update for the fuel mapping.
