with my boost controller switched off, it will run the minimum the wastegate spring/preload allows, so long as there is no damage to the wastegate lines.

that would be consistent with wastegate functioning correctly :) What pressure wastegate spring limits your boost?

I have often wondered about Wastegate actuation, as over time vacuum drops in an engine and the wastegate seals wear. So unless you constantly adjust it the boost control will lessen over time - good reason not to buy used wastegates.

On a far less serious note, and in response to 2.1 bar boost. In a modified GTIR years ago a friend used to boast that his engine could handle anything failing, so another friend told him to disable all boost control (wastegate locked) and remove the knock sensor for a 10 second full throttle blast. The thing went like a rocket - didn't blow up then, but one week later he called for a tow as he had just played catch the conrod. Motor pulled down and bearings were mushroomed and block had an awesome porthole. :)

lol......epic fail to that Gtir.

Having said that 2.1bar is no laughing matter

Yep, he was initially really happy about proving the doubters wrong until the engine died.

2.1 is high. I remember years ago hearing that Rigoli was ordering 5 bar map sensors, as the 3 bar were out of range on the racecar.

yeah those Rigoli boyz were truly nutz!

I remember their 4WD Hyundai Accent which ran 10secs or less

Waz crazy what they did by transplanting an Evo drivetrain in that chassis........but it worked!

That was the exact car - good memory :) the rumour was 43psi. I think it had a T60 or T70 Turbonetics custom turbo from memory.

Yep. Good times mate.......good memories.

I also happened to own an accent att when they did that lol

Turbonetics rings the bell as well.

Pretty sure I have a FastFour Mag somewhere about it

1.7 bar spring, lots of preload, did a few more tests consistent 2.08 - 2.1 bar, so needs to be backed off a tad.

so wastegate spring 1.7, no boost control gives 2bar? Boost creep?

      RB25DE NEO with Haltech ECU

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
