    Re: Softronic 981 Software

    I do believe that the chart which ticked you off was not for a 3.4L 981...and Softronic has a good product. But 360 HP from stage 1 is your typical mild exaggeration that is so typical of tuners. It...

    Doesn't look like it, sadly. Plumbing looks fundamentally different in terms of inlets and outlets. 4 holes on the engine side for the GT3, 2 for 981.

    There's an $850 sump extension from Mantis that I think would perform similar to the deeper billet sump. (adds 2.3 litres of capacity)

    Start by measuring real world acceleration. Rolling start on level ground. If power is really off by this much then the numbers will be noticeably off.

  27. Re: Engine cooling next step after 3rd rad. larger oil cooler or deep sump
