I think twice with BMS stuff, had it for my N52. Started to get weird engine lights and my cat sensors went cause the PBX was running too rich.
Piggyback's suck. 
But if something from Hartage or Kellener I would trust. |
N52 is a little different. Not turbo.
I've had a BMS tune on my n55 for over a year now and have not had a single issue.
If issues were present to the extent that we should be thinking twice, I think the thousands of jb users would have made it clear.
