typo ... oops.

Yesterday's tune on a MY04 STi. Owner had recently bought the vehicle and booked it in to have the driveability problems fixed. On closer inspection, previous owner had removed the the Vi-pec ecu that was in it and put back the stock ecu. The front AFR and rear O2 sensors were also not present. (Vi-pec does not require the use of these sensors). Both AFR and O2 CELs were deliberately removed via a reflash to prevent the engine light from turning on.

In real terms, closed loop was not functioning at all.

Anyhow, both sensors were replaced and we proceeded with a tune.

Recent Tune on an MY09 GH WRX with VF52, 3" TBE, 3-port valve and Process West CAI

Power and Torque were 288hp and 444Nm with boost set at 1.3bar @4500rpm and tapered down to 1.05bar @6500rpm.

Recent tune on a MY09 WRX. Vehicle already had a prior tune and we were commissioned to fine tune it.


We also took the opportunity to do a before and after run on this vehicle as the owner supplied an AEM CAI.

Initial Power Run with stock air box vs CAI on MY09 WRX:


The result was 262Hp and 371Nm @1.1 bar. Would have loved to go 1.3 bar and more timing for a smoother and higher power and torque curve, but we kept it at 1.1 bar as we were commissioned for a fine tune to improve on the power and torque on low boost.

Recent Flash Tune on MY12 WRX. Vehicle had a COBB CAI, upgraded boost solenoid, XForce TBE.

Results yielded 283Hp and 407Nm @1.2bar.

Blitz SBC ID and Process West Top Mount were installed with a flash tune. Flash Tune yielded 269.7Hp and 408Nm.

Recent Tune on a MY06 WRX. We were commissioned to install the Process West Top Mount, Apexi Intake and XForce TBE.


This vehicle had a power run done at Evolution R in 2011 and has since changed hands. Tune yielded 261Hp and a massive 450Nm.

Today's Power FC Tune on a SAUWA Skyline R33 GTST.


Mods included Apexi intake, Front mount and Apexi TBE with HKS 550cc injectors. Boost was set to 1.2bar on the HKS GT25 Turbine. Note: More timing at the top would have been great to smoothen out the top graph but factory internals so did not want to push it.


Evolution R uses Apexi FC Commander PRo Software to tune. This applies to both other and current model Power FCs.

Today's tune on a JZA80 Supra Non-VVTi. Mods include HKS 272 In/EX Cams and Gears, Full HKS Exhaust TBE, Trust Greddy Intake, Greddy T88 Turbine, Blitz SBC-ID Spec R and Hatech ECU. As always, we use Cusco 10W-50 Engine oil for clean and reliable lubrication.


Tune produced a whopping 613Hp @1.9bar of boost and 702Nm.
