2.8 pulley 60#injectors

I just put a 2.8 pulley and 60# injectors, and got it tuned by hp tuners. It is not consistant though it runs real rich some times. It feels like its hesitating, I was wondering if anyone else with the same setup has had problems?

Did u go a step colder on the plugs. They may be fouling out too, especially if it is so rich.

what is your a/f ratio? You need to flat line it at 14.7 then go from there.
