I need purchasing advice

[fastsvo]

Hey guys,

I am totally new to the Diablo line and I see plenty of used chips for the A9L for sale online. My question is which ones are currently supported by most tuners and the ones I should avoid? So far, I have seen red branded chips and black ones (stickers etc). Do tuners tend to frown on customer supplying the chip?

Thanks in advance!

Most tuners will want to work with the black chips.
