      • Hello Mike, your custom tunes should have been loaded on the tuner before being shipped out to you unless you requested the tuner be shipped out without them. In either case, you would have received a tune survey email for you to fill out. If you did not complete a survey and feel that you have received the tuner without custom tunes please contact Bama by calling in, emailing at, or you can request tunes by following the link below.

      Hello. Does this tuner provide real time statistics on screen such as HP, torque, quarter mile times? Or does it just show diagnostic information? Thanks!


      • This tuner will show the gauges in real time when you datalog. Unfortunately, there is no setting to see them separately. So when you datalog, you will be able to see your current RPMs, Boost PSI, Coolant Temp, Voltage, and so on.

        Having some doubts about the X4

        After purchasing the x4 for the price I was excited. I got my device and only the device. I did not get the box it was supposed to come in or wiring harness that’s supposed to come with it. I called American muscle and was not able to get through. I sent an email letting them know I needed the harnesses. Once I got them I was able to plug it into my car to tune it. But I was not able to use the device fully, as it hit 35 the x4 stopped working and wouldn’t function anymore. So I don’t know but I did not have the best experience with American muscle or the device. I don’t think I’ll be ordering from them anymore.

        Comes without download. Bit confusing on downloading tunes to unit. Could be better instructions. Otherwise, wow what a difference in throttle response and power. Gonna need more tire in the rear than stock size for sure.

        Nothing but issues, very disappointing

        Very disappointed. I received the device, the custom tunes were not preloaded, which led to a great deal of confusion and delays. Then they emailed me the tunes, I transferred to the device according to the instructions, and I tried again. The device got halfway through, said it didn’t have enough memory to continue and stopped. Again, more confusion and concern that this thing may have messed up my car in a serious way. Luckily it didn’t. I took the tuner home, linked it to the computer again to make sure that the tunes were loaded and device firmware was up to date. I then tried a third time, and what do you know, again the device says it has no custom tunes loaded. Now I have CAI which requires a custom tune for the car to run properly, and for over a month I have not been able to get the tuner to do its job.

        I originally bought the tuner expecting just more I guess. It's not the best tune company but it's affordable and I love their flash tuner. I bought this for the free tunes for life I plan to use it for all the small installs "exhaust, instake, cam, etc." However if your seriously like me and plan to run boost go for a dyno tune it's safe and way more beneficial! But for what your buying the bama tuner and free tunes for life is well worth it I'd recommend!

        Great value for money

        I started from 87 tune for aftermarket Roush axleback and BBK CAI. What has changed: amazing reaction for acceleration pedal, quick and smoother gear shifts what is starnge to me but I like it so much - I have better sound from Roush now! Maybe it is because the revs keep higher while accelerating. I don't know and I don't care - I like it a lot! Have some mods in pipeline, while definitely upgrade the tunes and use it again and again.
