Hi Sifu's,
my car just suddenly over boosting after i changed a air filter...
Will changing an air filter & b.o.v affect my car tune setting?
My current Low Boost set on 1 bar but most of the time boost meter shown...
After some thinking, i tot of changing my car piston. I'm using evo 1 engine now. Stock piston with big turbo setup. I'm afraid it might not last long.
My mech said use 1J or Fairlady piston, rebore...
