    Default DOWNPIPE Install DYNO (before and after)

    I have wanted to do this for over a year. My Fiancee was kind enough to buy me a protune and downpipe install form the best shop in our area Revolutions Performance.

    Car
    2008 EVO X MR
    Motor
    AMS FMIC
    AMS UICP
    AMS LICP
    AMS intake
    AMS test Pipe
    Synapse Diverter Valve
    GREDDY limited spectrum elite dual axleback (discontinued in 2009)
    DW 1200cc injectors
    DW 355lph
    Tuned at revolutions on COBB AccessPort
    MAP prototype downpipe

    The downpipe we chose was the prototype M.A.P. downpipe, or the REXPEED downpipe (they are identical and probably chinese) it is an 02elim as well.

    If you are considering buying a downpipe 02Elim, DO IT!

    Here is the Before and after!

    Before
    April around 50deg, 5,600ft above sea. dba--


    After
    May around 60deg, 5,600ft above sea. dba--


    Not only did we gain 17.4WHP, 30WTQ but the new design allows boost control to reap HARD and stay STRONG! Super happy about the results with this! Was well worth the money!

    Absolutely NO mods were changed between the times. This is simply a bolt on downpipe BEFORE and AFTER w/tuning!

    Hope this helps any of you and your decisions!

    Why no dump pipe? Nice gains for sure! I have an o2 eliminator as well and spools at 3100
