2006 GT stock idle rpm

[OLDSALTVA46]

Predator part #...339351.....9r09....2006 mustang GT

My GT is stock except for an S&B cai. when i install a tune, 87,89 or 91 octane, i tried them all, the car runs good but my mileage goes down by 4 to 6 miles per gal. when i load the stock tune back into my car then the idle rpm fluctuates about 150 rpm. The menu on my predator shows only a tune using the S&B CAI for a V6 mustang. How come there is no tune for a V8 GT using an S&B CAI. Could this be the reason the car won't idle right in stock tune.? thank you for any help that you can give me on this problem.

Yes, you need a tune for the S&B intake, we never got one for GT development, but you can get one from any of our CMR tuners of try one of the CAI tunes that is similar in design.

Thanks

Okay I have an 06 gt and during one of my revision updates It had an S & B tune for that cai. So if your saying that you never got one for the gt development what tune do I have that says S&B tune?? ummmm.... I guess thanks for TSS who I got a custom tune from. But I ran the S&b tune for a long time. So was it not an S&b tune?

Should be there. Plug tool into vehicle and go to options -> show calibration id

Make sure the key is on.
