dut dut dut dut, so it's it like suuu tututututu? hahaha?

i believe that's compressor surge sound, not nice.

no need for the BOV anyway, ditch it. for your power levels, and most people's, it's useless.

haha yeh id ditch it if it had a problem, bought the car with it on there. Guess it still doesnt solve the problem of the surge while on boost. Wrong turbo for my engine I guess.

BOV's have caused many a problem in the past, and will continue to do so.

At least whilst you're trying to figure it out, it's one extra thing to tick off the list. Get rid of the BOV and put a stock one back on

yeh will do, is there any particular trick to putting stock back on or is it relatively basic?

i can't imagine they'd be much $$, check the for sale section, i reckon you could pick one up for cheap-as-chups - people probably don't even think about selling them

I think youd be suprised on how fast they get taken. Tried a few wreckers yesterday and to no prevail. They all got non turbo 34's in and thats all :woot: can you use r33 gtr or 32 gtr BOV??? any modifications required

Dyno charts are in as attached. It seems that nothing is wrong with my car the turbo just doesnt suit the engine. The car started a day or two ago with the VCT playing up which was eventually all soughted out. Everything on the car was checked from head to toe, compression checks, boost leak checks, the whole lot and the car passed everyhting. We even tried a manual boost tea instead of the AVCR and it made no difference.

The car ended up making another 40hp on the last tune reaching 206rwkws :S and 1200Lb of torque. The car would ping anywhere over 13 degrees of timing and the power curves on the dyno charts are as good as they can physically get. U can see on the chart where the compressor surge is hitting, killing boost, torque and the whole lot. Top dotted lines are boost readings.

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
