They are known to have high rpm break up issues in the 5.0 world. There is another member on the board locally who has a fox body mustang with a warmed over 5.0 which makes 325whp on a haltech box using the factory tfi stuff. He has consistent breakup issues at 5500-ish rpm. After talking to a well known 5.0/haltech tuner, it seems like this is a regular thing which happens.
