"With less than 5 minutes of Livernois X-Treme Cal uploads, my G8 runs amazing and a wonderful complement to the mods I've already done. I've never been in an automatic car that can spins tires shifting in 2nd as well as 3rd, now I own one!!!! I'm just amazed on how docile it is, but when you put your foot down, it's one hell of "family" car!!! Or as the guys on Top Gear say on the BBC, one hell of a Saloon!. And thank you very much for the prompt response!! I did not expect to get the tune back the same day I sent you my stock files. Now I'm glad I've chosen your company as the go to shop for my current and future mods to my G8. Happy customer, Jason" - Jason
