Master-tech skill, tuner-shop range.
Rav spent 7+ years as a Nissan master tech and 10+ years deep in JDM. RSpec brings that discipline to cars that deserve more than dealer service.
Dealer-grade diagnostics
Nissan Consult-III+, factory scan tools, and the judgment to use them. Real answers, not parts cannons.
Calibrated to your car
Every tune built from your datalogs, your fuel, your sensors — on the dyno and validated on the street.
Built on JDM
R35, Z, Silvia, Skyline. VR, VQ, SR, RB. If it came from Japan, we know its platform cold.
Services built around the Nissan & JDM platforms you care about.
From bolt-on tunes to built-motor packages, corner-balanced chassis work to dealer-grade diagnostics.
ECU Tuning & Remaps
Custom, dyno-verified calibrations on EcuTek, Cobb, UpRev, and factory Nissan platforms.
Dyno Tuning
Load-cell dyno tuning with before-and-after graphs and a calibration you can trust.
Turbo & Supercharger Builds
Bolt-on upgrades to full built-motor forced-induction packages. GT-R, VR30, VQ, SR, RB.
Suspension & Chassis
Coilovers, bushings, alignment, and corner balancing for street, canyon, and track.
Brake Upgrades
Big-brake kits, pad & rotor upgrades, stainless lines, and proper fluid flushes.
Exhaust, Intake & Bolt-ons
Tasteful, tuned bolt-on packages — not just noise.

“Rav tuned my R35 after two other shops left it unsafe. Cleaner idle, safer knock behavior, and a dyno graph that actually makes sense.”
“He treated my 350Z like his own — explained every choice, pushed back when I wanted the wrong part, and the car is faster and more reliable than ever.”
“Went from daily to HPDE in one season. Corner balance, brake upgrade, and a UpRev tune. The car talks to me now.”
Latest from the shop.
Build logs, dyno pulls, and the occasional late-night wrench session.
