Volo OBD tuning chip

[Fluxcore]

Has anyone tried one of these out yet ? I just ordered one because , well , I was thinking it can't do any damage
And if it works on a xc90 that only has a rebuilt trans. With a shift kit in it I may make some other slight up-
Grades . I am going to cat-back and replace the air filter box with a better flowing filter setup.
I know I ramble but I hope you get what I mean .
Just wondering if any one on this board has tried one of these volo splice in to the OBD wiring harness chip
Setups yet.
I am going to , and if you would like some feedback later I can try to give you some .
It wont be much other than mileage and personal obersvations though.
