personally I think I'm heading to DOC VU
do you consider it a low-end tuner?
I watch closely what he does, it seems really serious to me
I have no opinion about Doc Vu. Never seen logs or dyno runs posted.
The only thing i see is that his main business platform is FB by spamming kill videos all day long. But if he gets many customers this way... why not. I guess this is also how he got your attention.
