Ratings and reviews

I've edited my original review from 1 Star to 5 stars. overall stability is much better. only annoyance now is having to resync every time before I use the logger or it just freezes. the main reason I bumped up to 5 stars is due to absolutely amazing customer service. ended up getting a stage 2 map that had to be custom made and it was ready the next morning and it's infinitely better than the TWO previous "professional" tunes I had done over the past year. More power and no timing correction!!!

They don't bother replying to your emails for over 15 days. Multiple emails sent but no response. Their tune caused the car's gearbox to jerk like it will fall off the car. Flashed the car back to stock and asked them for a refund. But it's been over 3 months and there is no refund and they reply to your mails once a month.

Awful support. When I first bought the app + tune I was told to use an ENET cable. I tried for weeks with support to get the ENET cable to work but unfortunately android doesn't support static IP setting (which is required). Support advised me to buy another OBD - USB cable ($50) and it worked! Fast forward to a couple of months ago when the app was updated and guess what?? They cancelled support for the OBD - USB cable, and you can only use ENET. Which doesn't work on my Pixel. I've submitted requests but the developers haven't responded. Waste of hundreds of dollars.
