When you buy a kit like the Fmax(turbonetics) or Greddy, what is the ratio on the RRFPR?
I would think adding a RRFPR in a 1:1 ratio to any kit would ease in the tuning department. Correct me if i am wrong, but for ever 1 psi of boost the fpr goes up 1 psi. In turn when tuning you are not having to sort of max out the piggy back at each rpm.
