Diablosport Trinity 2 EX Tuner (11-14 3.5L EcoBoost F-150)Find parts that fit my vehicle

Love This Tuner

The amount of power is unreal and the MPG went. Up tremendously I highly recommend this tuner

It's OK overall

It looks good and seems to do what it should but it's flawed. The customization screens are bad. They're difficult to figure out because they all say something like default under every gauge. It should say what each gauge is specifically. The other thing that annoys me is that it freezes up quite a bit when you try to load different screens. It requires unplugging and restarting. And none of this is new. I've seen these issues in reviews that are years old but I just hoped that the company would have figured out how to fix it by now.

Not exactly what I thought

I used to have the diablosport predator 2 tuner. But was unable to download custom tunes to that. So I upgraded to the Trinity 2. And out of the box with an update I program my truck to the 91 octane tune and noticed I wasn't getting second gear barks like I was with the predator 2. I'm not exactly sure why that is. But one would think same brand tuner same truck same preloaded tune should be the same. But it wasn't. Now I'm calling around shops to try and have them create a custom file for me to download to the tuner and finding out a lot of shops only deal with SCT tuners when it comes to Ford trucks. I don't know where I can take my truck to have a custom tune made for Diablo sport tuner. And here's a second issue. There was an update not long ago so I program my truck to stock and it said it was successful. I update my tuner go back to program the truck and now I'm having misfires. Check my spark plugs check my coils my wiring harness everything is good. 2 Days later just before I get ready to have my truck towed to the dealership. I unplug my battery to reset my truck's computer and see there's another update for my tuner. For some reason the tuner didn't save the factory settings of my truck correctly,don't know why but it just didn't. However the update that I recently did two days after updating it fixed the misfiring problem. But I'm unable to run my truck on factory settings because it didn't save the right settings. So my truck has to be tuned or to run stock I'll have to have Ford update my PCM. But other than that I love the screen the data that shows me. I'm not seeing it's worth so far.

Do not buy this product

The product is faulty. When product arrived it updated and only worked as a monitor and not a tuner as well. Do not waste your money. You are not able to tune your truck or car with this style of "tuner"

Diablo tuner

Easy to install but couldn’t get the tuner to update with WiFi. No problem used the computer and worked great. What a difference!! Woke my truck up!!
