so i have a 94gt with tfs1 cam,1.6 rr,cobra upper and lower with a 1in spacer and a mail order tune from dirtydirtyracing.com and 16* timing..he set my idle to 750rpm but it idles at like 1k rpm and will sometimes drop to around 750 but will jump right back up..what could be causing this?i can hardly tell my car has a cam cause of where it idles..any ideas?

Car should not even need a tune with that setup, and why the spacer for the intake the runners for the cobra are long enough.
