^^^ My OCI avg.15k Running Cobb stage1 93 map, max boost is still 16.2psi up to 174k. Original motor & turbo are running like new with no shaft play.. Now I want stage 2+, GMS Crossover & UP pipe, & LW crank pulley & heat shield. Invidia DP & V2 cat back, Perrin TIH, Racer X FMIC. With running Cobb stage 2 93Oct. map. For the last 3000+ miles. Waiting upgrade stage 2, 93 Oct. AP map from Tuning Alliance.
I'm very happy with the reliability of this car at over177k, with AMSOIL lubricant protecting everything.
