well since you aren't using the oil pressure switch i wouldn't think it would make that big of a difference, if any at all. yeah it wont' FEEL too much faster than the a6 but it is.. or it should be.. i found that out after i raced my friend before and after the swap.. probably a good 1+ car gain i had on him..

btw what do you have the fuel curves at? or can the fields controller do that? i'm not too familiar with the fields.
