Had the pleasure of tuning this 2012 Civic Si -- customer came in complaining of drivability issues on the current tune. Got those ironed out (got a text of "Car's driving way smoother", that's what I love hearing!), and got him a bit more power in the process.

Small turbo setup -- Precison 5431 .63 a/r with a 3" exhaust, stock manifold, DW EV14 1000cc injectors (compliments of VitTuned), DW65c in tank fuel pump. 11.5psi tapering to 9.5psi with a manual boost controller.
