I'd be willing to bet there is a little boost spike there due to the EBC gain being ramped up as hard as possible to get it to come on sooner.

Although it spikes hard there Trent usually removes some timing at that point to counter it.

I'm guessing the drop is the gate cracking and losing a tiny bit of pressure for a second

my old car has had a similar graph however not as extreme, it's a lot more obvious due to the hub dyno, on a roller it's there but not really visible on the less accurate graph

Mine never actually went back in time like Tony's DeLorean, but the more boost we crammed in the closer it got.
Dont have any of the ~22 psi runs as we detuned it afterwards

a week or so later on a DD roller it left a perfectly flat graph

why ask for recommendations, you'll only end up spraying them some other colour then hating them like the last 2 times.

In any case you'll probably end up spraying them whatever colour is the latest pranceworks craze, like some heinous satin pastel green mint or some other equivalent swaggotry

    • So for the wide band is a Bosch 4.9 correct for the Link G4+ along with a Can bus? Just get the Link gear or is generic ok too? Eg here: LINK LINK DIGITAL WIDEBAND CAN MODULE WITH BOSCH 4.9 SENSOR : KYP Performance House  
    • Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.
    • I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators. 
    • Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?
