Finally had a chance to scan my dyno runs -

11LBS AFR Taken at each exhaust (Twin System) (Possibly injectors need cleaning, as the run was terminated due to the knock count going up to 50)

15Lbs Boost 336HP - No knock issue

20Lbs AFR (Not sure which exhaust?) - Run cut...too much knock, up to 50

11Lbs Boost 300HP

12Lbs Boost 308HP

14Lbs Boost 325HP

By my calculations, the 20Lbs run reached 169km/hr in 4th, generating 380HP. The run shown earlier in the post but in 2005, looked like it would have had 10-20hp more at the same speed in the same gear. Possibly the dyno? Possibly my calc?

Noticing at 20 psi it seems richer,

so looks like the tune richens up with more boost - you might want to get a afr done at 15psi - no knocking sounds good, if you can save money without spending more on a retune.

The power graph is smooth enough.

Might be worth checking if the timing advance also lessens when you wind it up to 15psi.

Had a quick read through and one thing I think everyone is missing , correct me if i am wrong ?

The tuner said there was too much TIMING !

The problem is.....

How would he know unless he's played around with the timing to see where it stops making power or starts to knock?

    • Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.
    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
