I just bought a 2000 jetta tdi.
It has 435000 kms. It came with a kerma q loader and a tune already on the car.
I'm a little co concerned with the boost. It's over 25 psi but I dont know what to do with the tuner. Here is the ECU Info

038 906 012 bed
1.91 r4 EDC
G300
Sg 2507
Edc15v

That mean anything?
I'm looking for economy not performance
Thanks
