GIAC Stage 2 and 2+ software upgrades for the MK7 Volkswagen GTI.


GIAC Stage 2 and 2+ software upgrades are now available for the MK7 Volkswagen GTI. Stage 2 requires a turbo back exhaust upgrade, and needs an intake for maximum power gains. Stage 2+ requires a turbo back exhaust upgrade, intake and upgraded intercooler. These software upgrades offer dramatic performance improvements over factory software, while retaining factory-like drivability. On 91 octane fuel, performance gains were 80-90 wheel horsepower and 95-100 ft. /lbs. of torque. In certain areas of the power band, gains reached as high as 91 wheel horsepower and 104 ft. /lbs. of torque. As with our stage 1 calibration, our software features a proprietary boost control system to optimize air flow and horsepower. Our engineers have developed this calibration to ensure smooth drive quality and no issues with surging, turbo over speed, ESP lights or limp modes. For DSG models, we've spent a great deal of time combating power loss across shifts, specifically the 3-4 gear shift.
Other notable features include the following:

  • properly calibrated air/fuel ratios
  • improved throttle response for a drive-by-cable system feel
  • raised speed limiters to factory redline in final drive gear
  • optimized torque control for smoother, faster shifting with consistent power across all gears
  • free upgrade for existing Stage 1 users, same cost as Stage 1 for new users

GIAC's Flashloader handheld switcher is available for this application, complete with the following switching options:

  • 100-octane performance
  • "Stock" performance
  • Valet mode
  • Privacy Firewall

Stage 2 versus Stage 1 versus Stock:

  • Stage 2 gains over stock: +83 horsepower / +96 ft. / lbs. of torque at the front wheels
  • Stage 2 gains over Stage 1: +40 horsepower / +49 ft. / lbs. of torque at the front wheels

Maximum gains over stock: +91 horsepower / +104 ft. / lbs. of torque at the front wheels

Stage 2 versus MK6 K04 Extreme: Compared to the most power K04 calibration available for the MK6 platform.

  • -1 horsepower / +28 ft. / lbs. of torque at the front wheels

Real world performance testing: Recently, we drag raced our in-house MK7 GTI at Famoso Raceway on 3/1/2015 . We ran a best time of 12.608 @ 111.8 mph. For consistency, the car also ran back to back 12.62 @ 111.5x mph times as well. This time was run with the car making 294 horsepower at the wheels and 340 ft. / lbs. of torque, on 104 octane fuel.
After our 1/4 mile testing, we incorporated some changes to our calibration that brought 91 octane performance gains close to what we were making on 104 octane fuel. This was done through code changes that did not include alteration of the knock sensor filtering. Stock knock sensor calibrations are used in all of our MK7 programs.
Stage 2 versus Stage 2 Race Beta: This is the calibration that ran 12.608 @ 111.8 mph.

  • - 10 horsepower / +13 ft. / lbs. of torque at the front wheels


NOTE: None of our testing involved the use of a boost tap that removes the intake air temperature sensor from the direct path of airflow. We found that use of these can inflate dyno numbers due to artificially lowering intake temperatures forcing boost and timing higher than it should be for the conditions. Our stage 2 program is not compatible with boost tap designs that move the MAP/IAT sensor out of the manifold. Using a spacer like this with such an aggressive file may lead to turbo or motor failure. 


Thanks to our friends at GIAC we received some interesting video to watch. Enjoy!

Video of GIAC OBDport tuned RS7 vs a piggyback tuned F10 M5!

TAG Motorsports' GIAC tuned Stage 1 Audi RS7 impressed the crowd at the Airstrip Attack on October 25, 2014 in Coalinga, CA.  The event was covered by YouTuber

 Check out what he had to say about the GIAC tuned RS7 in his review here:


GIAC OBD port software is now available for T5 20TDI Volkswagen ® Transporter.


GIAC OBD port software is now available for T5 20TDI Volkswagen ® Transporter.

GIAC performance software is now available for the T5 Volkswagen ® Transporter 2.0TDI with an ECD17 ECU. This software calibration accommodates the factory exhaust and intake system. It offers significant drivability improvements and dramatic power gains over the factory software.  Peak to peak performance gains are measured at 50 crankshaft HP and 100 ft lbs crankshaft torque over stock on a 5 speed manual.  This performance program is flashed via the OBD port with proprietary GIAC flashing software at GIAC authorized retailers.  The ECU is never opened or removed for installation.

Thank you to Steve Pinson at Statller for his support with dyno and road testing.

Other notable features include the following:

* Torque curve specifically calibrated for the 5-speed manual gearbox.

* Improved throttle response for a drive-by-cable system feel.

* FULL ECU flash (not a simple map flash), so software updating is possible with the GIAC system..

* Low smoke flash, ideal for particle filter equipped models.

The software purchase (MSRP $550.00) includes a GIAC Pump performance program. Please flash with GIAC Serial Suite 698 or higher and choose Gen 1 A.

The following ECU part number currently supported. If your part number is not on the list, ask your GIAC authorized dealer to submit a file request.

Usefulness of Engine Logging

Myth: My engine is already in good condition so I will not benefit from logging

Fact: Logging still comes in handy for preventative maintenance. Here is an example of bad fuel timing that goes unnoticed in virtually all cases. The following charts show before/after fuel timing adjustment:

The fuel timing issue tends to deteriorate gradually (possibly over the course of several months) and drivers will not notice until the problem becomes severe. By logging we can do preventative maintenance at once. Optimal fuel timing contributes to better power and reduced emissions.

A similar case applies to the MAF sensor, which is another common deteriorating item in some engines. It slowly reduces power until it becomes weak enough for the driver to finally decide that something is wrong. This could be prevented early by logging.

Logging also assists in fine-tuning boost control and other engine parameters during custom tuning.


Here is a real-life diagnosis & solution of a stock car BEFORE tuning:

Boost Control

We found overboost in logs that the customer was not aware of. Adding performance with any tune or product will result in even more severe overboost, causing early turbo failure. The customer replaced the factory boost controller and boost hoses, which are normal wear items.

Boost Control

There's an apparent improvement, but it's still overboosting. Engine logs revealed that the N75 duty cycle was a lot higher than normal so the turbo actuator was adjusted to factory specs. See the next chart for the result. His turbo was a 6-month old factory replacement with an incorrectly set actuator!

Boost Control

Now his engine is optimized for longer turbo life and it's ready for a great tune. If minor overboost or underboost persists, they may be corrected in a custom tune.

We perform engine logging on all of our customers cars who purchased Malone Tuning Software stage 1 and up. For more details please Contact Us directly via email or phone.


Modern tuning FAQ

I'll warn you now, this article might require a couple of reads and it will only skim the surface of aftermarket chip tuning. Most of the information here will be fairly general as every car; engine management system is significantly different. Hopefully you can at least have a better understanding of what chip tuners need to do to develop a product and how they go about modifying a standard ECU to create more power & torque
