I was reading modified mag and they talking about the new evo x and how if they modified it, it was sending the transmission into limp mode. that means any kind of mods even like a new tire. they have it tuned to shift at certain points and by putting mods on it it throws it off and is causing problems. But if the ones who are having the problems with the G8 don't have mods then I don't know. I just thought that this could be useful. I also heard that if anything is done to them that they should be tuned right after it is done so that this doesn't happen. Let me know if you have heard anything like this.
