REVIEWS ON TUNING MODULES
GAN GA +, GAN GTL, GAN GT

with Dynamic mode there are really better acceleration respond, convenient mobile App, easy installation. It’s good that you can use the same unit on other cars with the same engine type

Eco mode is doubtful, according to the fuel consumption the fuel economy is less than 5%, and not up to 15% as stated on the website. When calibrating using mobile app, the progress bar does not work correctly. For example, it reaches 48%, then rolls back to 41%, and such rollbacks continue while calibration is in progress. It is annoying.
