Need to purchase a tuner, as I am installing 295/70/18 tires. What is best and why? I have a 2010 4x4 f150 5.4. Any help is great! Thanks

SCT SF3. I just got tunes from SoCalDiablo.com. Shawn rocks. He is working with me right now on a 87 tune. Im trying them out to see which one I want and adjust from there. Great guy to talk with and very good at his craft! Call him up 562-305-3532 and he will help you out.

I've had great luck with Livernois. Both Livernois and Socal have their fans.

There is lots of info in this forum here: https://www.f150forum.com/f70/

Great topic. I was just considering the SCT SF3 as well. Thanks!

Lots of folks like the SCT sf3 simply as it has the three preloaded tunes on it but can hold up to ten custom tunes as well so you can try different custom tunes from different custom tuners

Got my SoCal tune for my SCT and holly crap! It freaking rocks! All smiles here! Do it with a SoCal tune. You wont be sorry! I also had a SCT with the canned tunes available and they were hardly noticeable over stock just an FYI. So I would say just get a tuner from a vendor who does custom tuning and be done. You can tell who I would recommend

Does the SCT re calibrate for tire size as well. I'm in need of a tuner as well. Have intake exhaust just need to finish it up.
