Injected Engineering

I have installed Frpp cams. Above 2000 rpms it rattles, idles fine but ones you get above globle it rattles i can adjust the timing a little and get more rpms before it starts but i'm not that good with this Diablo to know where to stop safely so i stopped. I have some friends who refered the guys at injected. so here i am. i'm in cartersville so if this sounds like a tune issue what do i need to do. Thank you for any help.

BY the way its an 05 Mustang GT.

Call me next week to schedule an apointment so we can help with your issue. Probably no big deal, we just need to take a look at it.

Thank you,
