Are you in Richardson, or Plano?
Hi 5Are you in Richardson, or Plano?
k03-053 turbo, no such thing as a "k03s"
And 10lbs is perfectly normal for a stock tune on this turbo. I think 9lbs is the official pressure for the stock map.
Thank youActually stock ko3s should boost to 11 psi. 15 psi and you'd be on a stage 1 tune.
