I'm merely an interested observer in this tuning thread, but I do find the fact that there is apparent animosity creeping into the discussion, a bit disappointing because it seems to stop members from posting their opinions or ideas and that means we all miss out. I have absolutely no idea if tuning affects CVT transmissions, ..... but can I respectfully submit to you that if you have only been tuning your car since November, then it's probably a bit too early to say that the CVT is unaffected ...... hopefully in 5 years time you can say the same thing. Again I repeat, ... you might well be 100% correct in your statement about tunes and CVT, but I'm not sure it's fair to call it BS if someone suggests that there might be problems down the track. It might not be deliberate "false information" ..... it might be just an "honest opinion" ...... and you only have to read through a few different threads on this forum to see that opinions are like Aholes ..... everyone has one
