i'm seriously considering getting a tuner. who to get it from and which brand? i'm sure there will be a mixture of references, but a guy here locally was kind of reluctant to do it for a 'focus'. i guess 'coz it wasn't worthy? or maybe my $420 wasn't worth it? he was endorsing the XCAL3 but only seemed interested in mustangs. i guess i have to look to the mainland...
