Can someone shed some light into this and or prove the legitimacy of them

 

They're real. And the gains are real. Know a few guys who have been tuned by him. They say his tune gives better mpg as well as power.

The one you want tho is this one unless you wanna do some crazy N/A stuff: https://www.ovtuned.com/products/sci...handheld-tuner

 

ive looked into the hand held tuner also and i hate the fact that its limited to the tunes that they provide you. the one i linked claims to allow you to do everything the handheld can do plus allow u to modify everything eles in between. i gotta see someone eles with this until i commit.

 

You can run a search on here for the Orange Virus tuner.. there's a lot of guys that have installed it and I haven't seen any bad reviews. The Mazda guys like it too.
