I just put stage two ***** Thumpr cams in my 05 Mustang GT, and I have the SCT 4x tuner, and I was wondering if anyone knew where I could find a custom tune? any help would greatly be appreciated.

Contact Bama tunes at American Muscle

If you want a custom tune, the best way is a shop that runs the car on a dyno.

Second best way is through American Muscle or any of the sponsored vendors on the forum as they can provide a semi-custom tune to take into account the cam. It's only semi-custom because they use your factory fuel map and modify it based on the cams characteristics. This gets the performance dialed in to about 80-90% of it's capability? the remaining 10-20% would be squeezed out for your specific car at a dyno shop.

Hi Koenig99829,

I would be very interested in the out come of your combination as I too have just installed MT cams (I have original Breenspeed tune in car), all of a sudden it seems sluggish all most stalling when I power brake (TCM off) or try to heat tires. I swear it feels like when I punch it in drive from start that it feels like starting in 3rd gear..................
