If you’re viewing this blog post, chances are you have an idea of the real world difference between off the shelf canned tunes and a complete custom calibration. For many, mail order calibrations based on vehicle notes (modifications/driving style etc) is the only option. Truth be told, the people that arrive to us with canned/basemap calibrations end up being lifetime clients once we’ve given their ECU a once over. Drivability is one of our biggest concerns, WOT is fairly simple in comparison. We believe this to be what separates us from the pack!

MOVING ALONG…..We had a great example of the contrast between the two tuning styles with Sam’s BRZ. It arrived to our shop with a mixture of small issues. Boost level was inconsistent, AFR was pig rich in various spots on the map, would die out in traffic regularly, choppy low speed/low RPM cruising, so on and so forth. From a mechanical standpoint, we battled boost levels a bit but ended up getting the curve where we needed it. On 7-8lbs of boost, we were able to churn out 315-320whp from run to run with great consistency. The turbo kit is a custom unit built by Driven Performance, and uses an internally gated Borg Warner, front mount, full exhaust, stock injectors. The kit looked to be great quality with much attention to detail. The FR-S/BRZ community has been one of our biggest supporters in recent years. We have invested hundreds of hours in seat time to learn these systems front to back, all in the name of passing that knowledge into our clients ECUs! For a calibration like this, give us a call M-F 8-5pm EST. Our schedule gets more and more dense closer to spring time, we will do all we can to get you on the rollers as soon as you need!
Cosworth brings the latest forced induction option to the Scion FR-S and Subaru BRZ: the Stage 2 Power Package. The Cosworth supercharger is a positive displacement roots style supercharger which provides boost at all rpm ranges, perfect for SCCA and driving styles that require instant response. The new FR-S BRZ performance supercharger package comes complete with a new intake manifold that houses two air to water intercooler cores.
The Cosworth supercharger kit is available for purchase now and we look forward to providing this kit, installation and custom tuning to Scion FR-S and Subaru BRZs looking for a performance increase.
With the installation of a Greddy Turbo Kit on a 2013 Scion FR-S along with supporting mods and dyno tune, we were impressed to achieve 315WHP DynoDynamics, more than double the factory FR-S BRZ wheel-horsepower! The FRS was modified with high performance parts including a Greddy Turbo Kit, Tial blow off valve, Dynosty fuel upgrades (550cc injectors and pump), over pipe, front pipe, and Dynosty tune using EcuTek. The FR-S gas tank was drained of pump gas and filled with E85. Greddy uses a Mitsubishi turbocharger, which is perfectly matched to the FR-S BRZ FA20 engine for rapid spool and practically no lag. This combination helps the lack of power normally found at lower RPM, and is a great street-car turbo kit. See the Greddy FRS Turbo Kit low boost verse high boost comparison below. The Greddy kit utilizes an internal wastegate, so more boost would require modifications to the internal wastegate or upgrading to an external wastegate. This Scion FR-S Turbo Kit fits great, and installs on Subaru BRZ as well.

UPDATED SEPT ’12: Dynosty turbo package achieves 409WHP on Dyno Dynamics at 16psi on Scion FR-S. Dyno chart below.
After tuning on 4PSI, a Haltech boost control kit was fitted to the Scion FR-S and boost level was raised to 9PSI. The result was a record-setting 324WHP 250TQ!
This turbocharged FR-S build consists of:
· Dynosty Scion FR-S Subaru BRZ Single Turbo Kit with Tial GT2871R Turbocharger
· Tial MVR 44mm Wastegate and Tial Blow Off Valve
· Injector Dynamics 850cc Fuel Injectors running E85
· Haltech Platinum Sport standalone engine management
· Haltech Wideband and Haltech Advanced Boost Control System
· Dyno Tune by Hal at Dynosty
