    going crazy. 14 FZS low boost after mods

    here is the deal. 14 FZS installed the following:

    Riva power filter
    riva manifold upgrade
    riva gen 2power cooler
    hks blow off valve
    riva cooling upgrade
    rd R2 ecu
    RD grate and plate

    after no more than 74 mph went ahead and checked everything again. Went back to the lake and worst, no more than 6500 rpm and 7 lbs of boost, had a gauge installed Engine is very smooth, compression is good. Just feels like drowned in gas, looses thrust power, or timming. As a note, the gen 2 cooler and filter were for a 2013. Please heeeeeelp, going nuts.
    Thanks
    Jay

    Have you pulled the vacuum line from your hks? Is it leaking? Mine came apart recently and I had the same boost level as you at wot

    You have a hose off, check the hose from the throttle body to the intercooler

    +1 on checking the vac lines. Also make sure you don't have it in L-mode

    Checked all and no leaks. Will go Back to test next week. If it does not go over 74 will send ecu Back to make sure they did it right

    IMO I doubt it's the ECU, feel around the bov is the oring installed?? Your not producing boost hence you are losing it somewhere!! Make sure that bov is operating correctly if it is not closing shut properly, it is the same as pulling a hose off

    boost leak. Throttle body connection or where it connects to the cooler from the throttle body.
