    Unhappy VVTi TT6 dyno run.....no where near stock figures

    Hey guys, today I decided to put my vvti tt6 supra on the dyno to see what sort of power it would make before I went BPU spec.

    Car:

    2000 Toyota Supra VVTi 2jzgte manual
    Kakimoto catback exhaust
    Hks intake



    As you can see it just about made 192bhp and the boost massively falls off after 3500 rpm which shows the 2nd turbo isnt coming on at all!?!?!
    The car had fresh plugs, oil and filter recently too.

    Any thoughts? Looks to me as a boost leak or vaccum leak? But I dont know where to start or look or how to even tackle the issue. Any help much appreciated!

    Put car in TTC mode. If you get boost across both turbo's then you know you are dealing with either a plumbing or VSV issue.

    Unless it’s the hose to the pressure tank then you still won’t get boost

    Right I'll get all the boost pipes/hoses checked along with the valve and vaccum hoses too, also a smoke test should be helpful
