This is the funnest tune I've ever had makes me enjoy my car so much more.
Performs as listed. Car is running well and is a bit more fun from coming from a unitronic tune previously.
the tune definitely has more pull, a lot more. its easy to install and is definitely worth it.
The tune is actually sick! The tune for some reason makes it shift really smooth and it’s actually pleasing to drive, let alone the fact that the car shoots flames now… the tune was not that hard to install, just go on YouTube, it’s on there. The tune definitely is worth it in my opinion. When in park or neutral and you rev to around 4-6 it definitely will shoot flames. The only down side is standing behind it literally hurts, and u probably will need to plug your ears!
I loved it, the 2step is insane, it changed my car, I went from a stock ecu to the stage 2, I wish I could give a 6 stars review.
Very professional! Customer service is great. Very helpful on answering any questions! Plug and play ! Since install with ecu it’s a whole different car. Very smooth and the power is definitely there!
