OK is there a tune you'd recommend and would there be a link to this site or somewhere else?
I was thinking of just running the 2.5 maf and not tune at first and put the 3.0 maf in and tune later.
But from what I've read here I'm thinking I better go with the 3.0 maf and tune.
Never tuned before. Thanks
