  • URS4 automatic trans turbo upgrade, how many have done this?

    Currently running PRJ chipset on my URS4 for the last two years, boost increased to 2.3bar, makes the car boost like it should. Stock injectors and wastegate spring.

    As always, wanting moar powar.. but I want low end power.

    Not concerned about high end power. The speed limit here in NZ is 100km/h and if caught at 140km/h+ I will lose my license.

    Thinking about installing a 1.9bar wastegate spring to increase low end boost.

    But I can't be the only URS4 auto trans owner who has looked at upgrading the turbo. Many high powered vehicles runs automatic transmissions.

    Would like to see some feedback from Auto trans owners who have upgraded the turbo and what was the result?

    How much torque after the upgrade and did it cause the trans to slip or what?
