EVOLUTION RACEWERKS | Your #1 GIAC Authorized Dealer and Installer

Evolution Racewerks is proud to be running an in-house special for all GIAC flash tunes!

With our 135i time attack race car equipped with GIAC for many years now, we can firmly conclude that GIAC is the most advanced tuning solution we have used for the N54 platform. Not only that, our in-house daily driven 335i is also equipped with GIAC stage 2 and it is the smoothest and most reliable tune we've ever had.

GIAC is often overlooked compared to other tuning solution because it has to be done by an authorized dealer or distributor, which is not as 'convenient' as simply ordering a tune. However, the level of sophistication and advanced principles of tuning offered by GIAC is well worth the extra step. The main reason that GIAC requires their tunes to be sold and installed by authorized dealers is because special training and software is required to properly flash the tune onto a car as it covers many more parameters that piggybacks and some other flashes do not cover.

Any tuner can claim they have the highest dyno numbers but that is hardly the tip of the ice berg when it comes to a proper tune. GIAC's focus is well-rounded with power, smoothness, everyday drivability, and reliability all taken into account. This is why we at ER believe that GIAC is the tune of choice.


GIAC is now offering multiple stages for the N54 motors, designed to meet the desired power levels of each individual car!

Stage 1(+67 HP and 97 LB. FT on 100 Octane)

GIAC's Stage 1 software is designed to make safe and optimal power gains without the need for additional modifications. Nonetheless, stage 1 software is compatible with hardware upgrades such as a FMIC, dual cone intake or cat back exhaust. On GIAC's in-house Mustang dyno, peak gains have been measured at 67 horsepower and 97 ft. lb. of torque on 100 octane fuel, and 53 horsepower and 68 ft. lb. of torque on 91 octane! Further, GIAC can deliver these results with factory-like drivability.


Stage 2 (+108 HP and 128 LB. FT. on 91 Octane)

GIAC's Stage 2 software is designed for cars with upgraded downpipes (high flow cat or catless) and an upgraded FMIC. While other supporting hardware such as an intake or turbo back exhaust is optional, it is strongly recommended for maximum power gains. On 91 octane fuel with an upgraded FMIC, dual cone intake and catted turbo back exhaust, GIAC has measured peak gains of 108 horsepower and 128 ft. lb. of torque!

Stage 2 Race (+125 HP and 146 FT. LB. on 91 Octane)

GIAC's Stage 2 Race software is designed for cars with full supporting modifications such as intake, turboback exhaust and upgraded FMIC, as well as water methanol injection. Perhaps most important with this stage is that it allows the ECU to maintain active fail safes. In the event of a knock or lack of sufficient water/methanol flow, GIAC's software enables the ECU to quickly take corrective measures so as to ensure that no damage occurs to your engine. Further, GIAC software is compatible with any water methanol system. (For example, the Berk Technology 135i currently runs GIAC software with AEM water methanol injection, while the Evolution Racewerks 135i runs the same software with a Snow Performance Stage 2 kit) With this software level, GIAC's in-house Mustang dyno has measured peak gains of 125 horsepower and 146 lb. ft. of torque on 91 octane!


For those who like to see big numbers, here is a dyno plot of GIAC's Stage 2 Race software on a Dynojet dynometer. With a peak output of 432 horsepower and 453 lb. ft. of torque (at the wheels, of course), you be be certain that GIAC software will make your N54 BMW one of the most powerful around!
