Maserati Quattroporte mbFAST ECU tuning + bubbling 70 hp more (by JMS cars)

Thank you for your assistance. This time we were asked to carry out ECU tuning and bubbling on a Maserati Quattroporte. We don't usually do business trips, but if you need to remove and install the ECU, we may go to your place if there is enough space nearby. The installation was carried out at JMS cars in Kawaguchi. The muffler has Powercraft in it so it has a bigger bubbling. The horsepower has been increased by about 70 hp and the sluggish feeling at low rpm seems to have been eliminated.

How would you like to try it? If you would like to try it, please contact us! Best regards.

We are also looking for shops to become our partners. For more information, please see below!
