        • When you order the Bama Tuner by SCT w/ Custom Tunes a 19 question questionnaire is automatically sent out to your email. After you fill this out BAMA takes the information and loads the tunes into the tuner and sends it out to you ready to go. If you have not received the email feel free to call in and speak with BAMA directly and they will go through the questions with you.

        I have a 2008 F150 Harley Davidson with the Saleen package. I have added long tube OBX headers, BBK throttle body and a QTP cut-out. I will be adding the ford racing cams and the SLP loudmouth exhaust soon and was wondering if this tuner would work on my truck? Thanks in advance.

        • Yes, it would be compatible with your truck.

        If I purchase this tuner for my 98 f150 4.6l do I have to purchase tunes to upload into my truck or does it come with preset tunes that have no additional costs?

        • This tuner will come with pre-loaded tunes at no additional cost!

        Can I disable the PATS star with this?

        • A preloaded tuner cannot offer this function, however a custom tune may be able to. I would just suggest to speak with the custom tuner of your choice to make sure it is something they offer, but it indeed may be possible with a custom tune.

            It does what it says

            It is pretty good, but I have new engine codes from the tune. I the price is pretty steep for what your getting though. Wouldn't recommend for the price.

            This tuner is great allows you to correct for new tire size, change shift firmness to your liking and even bump your timing for a little more power! Love it! You can use this tuner. I made the changes in stages just to see what each one did it takes just a few minutes each time.

            I have mixed feelings about this item. I wish there were more tunes for it even if you have to buy them. The canned tunes are okay, the most obvious gain is to be able to firm up and change the shift points at WOT. This has helped a little with performance.

            Easy Power Adder

            I would venture to say this is on of the easiest mods you can do, if you can operate a smart phone you can tune your car. It is a more tech oriented mod rather than mechanical. The tuner works perfect all the time. Helped with the shift point towing a dirt bike trailer over passes, motor seems to have an easier time of it now. If I had to be really picky I would say the only thing that could be improved on this tuner is the finish. The black plastic shell gets dirty and scratches easily, like most gloss black finished items. As always quick and easy delivery from American muscle.
