By target, do you mean higher than your actuator's spring rating? Try running a vac line directly from the boost source off the intercooler piping or wherever you're getting it from to the actuators. Completely remove the boost controller from the equation. You said with the standard boost solenoid in place, it made 8psi? If that's the rating of your actuators, I dare say that's probably the issue. While your turbos aren't HUGE, they're certainly flowing a decent amount of air and therefore exhaust even at that low boost, so I wouldn't be surprised if it was just simply overcoming the wastegate flap and pushing it open.

I've done that, and it runs the same 8psi @ 4k

If thats the case, does that mean I need a stronger actuator spring?

Wait, there's one thing you haven't told us: what is FULL BOOST? By that I mean, what does it make when you have the boost controller plugged in @6000rpm?

If you have 8psi actuators (that's a problem in itself, way too weak) and running it at say, 20psi through the boost controller, then the boost controller settings are the problem. I would assume that's a gain setting of some kind, sounds like it's letting the boost come on very very slowly after it starts having to bleed air out, which is causing it to climb from 8psi to full boost at a snail's pace.

So lemme get this straight, your mate has dropped $10-15k on an engine which is making ~700hp and he's got you poking around under the bonnet trying to diagnose a boost issue even though you're clearly not qualified and, with all due respect, probably are not the right person for the job?

Is your mate a total moron?! A $15k engine and he's not taking it straight to a well regarded tuned who is properly qualified and equipped to diagnose a problem which has the potential to destroy you mates big dollar build?

Dude! I'd recommend keeping that bonnet shut tight until youget it to one of the well regarded tuning shops. Seriously, if you think there is something wrong you'd be mad not to get it seen to by an absolute professional.

Well that doesn't make sense.....

There is NO WAY a boost controller can cause boost to come on LATER.

NO. WAY.

What if the boost controller is leaking boost? That would probably cause it to come on later, wouldn't it?

more info needed

apart from running a pair of Garrett GT 2860 - 7, we know nothing about your car.

did you buy the car like this???

what exhaust is on the car?

does it have a stock cat ?------- if so it could be severely blocked!!!!

what intake is in the car filters could be very blocked!!!

start with the simple shit

if you think cat could be blocked of has very small cat back exhaust unbolt it just before the cat and go for a quick drive (don't get caught by the cops though!!!!!)

Ok,

Trying to run 15 psi, the turbos were installed when the ones on the car when I bought it died.

I have an apexi power intake, hks super dragger cat back, factory dumps and an x force cat

So potentially the EBC is the problem, when it needs to begin bleeding air to raise boost above the actuator's base spring resistance. Like I speculated, this would be some kind of gain setting.

I'd say as others already have, time to take it to someone such as Yavuz @ Unigroup and have him fiddle with the EBC.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
