Phazer MCX turbo idle question

[mxbulldog]

I installed an MCX phazer turbo a couple of years ago. Since the installation of the kit, the idle is really low. I cranked in the idle adjuster as far as I can and it settles out at only about 1600-1700 rpm once hot. The sled also has some issues starting in the cold as well when it is really cold and the sled has sat all night outside. Inside my heated shop it fires as fast as it ever did stock.

To add to the information, I am running the headshim and always on 91 octane premium pump gas.

Anyone have any experience or suggestions on why I have no idle adjustment left and if there is anything I can do about it?

Thanks,

Your problem is caused by the lowered compression with the headshim. I had the same trouble with mine.

that is kind of what I am thinking as well.
