So I just joined, I have a base 2015 GT Performance Pack car and currently run a aftermarket tune with an SCT X4. Seems like all the tuners out there including Lund are having problems with the torque management making the cars have a hanging rpm after shifting issue with some aftermarket tunes. I use a different tuner and my tune does the same thing and no one has been able to fix it yet. I was talking to a friend and he brought HP Tuners, and just so happens I have another local friend that has been playing HP Tuners for quite a while ... mostly for GM applications but was starting to mess around with Mustang GT's and Ecoboost F150's. We were starting to do mess around with my F150 last year but something was wrong with the software and we couldn't get the tunes from the truck...anyways, I don't have the truck now and I think I kind of want to try the HP tuners software and learn how to do my own tunes maybe. My car just has a CAI and cat back exhaust on it for now with a 91 oct tune, but I am picking up LT's and plan on running E85. Has any software been released for the 2015 Mustang GT's yet and if so what kind of prices would I be looking at to get the car running on HP Tuners? Is there a decent base tune or would I be doing all that myself? Sorry for the newb/dumbass questions before 10am on a Wednesday morning lol.
