Yeah i believe im going to go with a mechanical gauge, much cheaper also. Yeah ive briefly read into the OBDeleven and what not, but yeah im feeling the mechanical vent gauge like yours
Well finally got my first wave of shit done to my car, got the res delete done, the GFB DV+ installed, and I got my wheels painted. Now for the AC compressor, boost gauge, and intake.
The DV seems to have cleared up my issues only drove it for about 25 miles after getting it installed but can definitely tell a difference.
