How is your fuel pump wired? And how is the A/F ratio and injector duty cycle?
I am asking because I had an episode with my pump not getting enough voltage. The A/F ratio was fine but injector duty cycle was maxed out prematurely, and I lost about a good 40kw.
Fuel pump is getting getting 12v that was checked when on the Dyno. Not sure what the duty cycle on injectors are I’ll find out.

I’m changing to a 3.5inch x force exhaust now and also doing a cooler pressure check, dare say I’ll be changing the cooler I gained 25kw just in exhaust restrictions so far. What’s to say my cooler isn’t stuffed at this point.Not gonna throw money at springs and cams just yet I’ll do a power run and report back also on the last run it had some slight mis fire on the 292kw run coil pack harness seems to be the suspect as I have brand new coil packs
-
Ok so I took the cat straight off back on the dyno made 292kw boost spiked half a pound so there wasn’t much loss between previous run of 282kw with de cat and exhaust. I was expecting to see boost come on quicker still took until 4100-4200rpm. I’m being told valve springs are the issue and change the cooler

Yep, maybe the catback section to the muffler is more restrictive than the cat itself. Needs to be dynoed with front pipe only as I originally suggested and done myself to get a clear baseline of what's what. Are they saying they won't dyno it like that ?
Currently making them do that right now

If they won't dyno it with the exhaust dropped do it yourself at home.
Yeah I will do that for sure
-
Ok so the car has been chucked on the Dyno and it pulled 282kw with the de cat still a bit of where it should be

I don't know what cat he's running but the current 80mm Apexi super cats are 130cpi which is awesome.
They are also $1200 - $1400....
ouch.
That’s what I’m running I didn’t buy it new it was used

Did you read my post from 10 years ago ? Unless you have run it on the dyno with just the front pipe any visual inspections of it being ok are purely just speculation. My cat "looked" ok. Run car on dyno and barely made any power as mentioned. Mid range was pathetic compared to what it should have been.
We then jumped straight under the car, unbolted the exhaust at the front pipe and let the cat back just hang there under the car, so the exhaust was purely just the manifolds, turbos, dump pipes the into front y pipe. Run it without touching anything and car went straight back up power. It was 360ish kw from 250ish kw, but Remember the exhaust was completely open. Sounded awesome. The build to boost was also affected by the blocked cat, making the car build boost really, really slowly. Your boost curve looks very slow to build, which it also pointing to excessive backpressure. I dont think your problem is as bad as what mine was. With no restriction the turbo should go from 0 - 20psi in around 1000rpm - 1500rpm when nailed. Power range depending on dyno type with 98ron at 22psi should be anywhere between 290 - 350kw with a full exhaust fitted. I've noticed around 310 - 330kw generally on different dynos. Max boost efficiency is 1.6bar for GT-SS / -9 turbos so about 23-24 psi.
You better hope its your cat causing it or you have way bigger problems somewhere else to worry about.
Hey mate yes I read your post, I agree with what your saying the tuner wants to triple charge me on off the Dyno etc.So it hasn’t been the easiest thing to deal with. I am gonna delete the cat and have a straight through de cat I should see a big change With a de cat on the Dyno. If it’s not that then I do have big problem and I’ll be taking the car back and probably start looking at the cooler next

I will just leave this here....
So have you dropped the cat yet ?
I have told the tuner to drop of the cat they have just told me it flows much better, they think cat is fine. They didn’t chuck it on the dyno yet, im taking the punt and ordered a de-cat and will be doing a power a run with it and see what I get it atleast rule that out hopefully it’s the cat. They checked the exhaust from the cat back said there was no restrictions in it anywhere either.

Have you got a chart showing boost?

the start of the drop off is just before 6000rpm

Something is wrong but its not the intercooler. I have a stock r32 rb26 making 245rwkw on e85(12psi). And an rb26 with single turbo making 520rwkw(26psi) with the stock r32 gtr intercooler.
I would be doing check for boost leaks, rag in the intercooler piping, timing off , timing belt off and compression on motor.
Even on pump fuel 20psi with those turbos should be a lot more.
Oh and double check you actually have gt-ss turbo's
I'd also consider another tuner, specially if he offered to sell you an intercooler
Yeah I’m gonna do a complete check of cooler pipping flow is being chocked off more I think of it can’t be the cooler it might be a possible a rag or something is stuck or my cat may have a blockage. The tuner did the timing checks, They are 100% gt ss turbos

What did the tuner say ?
How big is the cat?
How big is the exhaust at its narrowest (typically at he rear muffler)?
Tuner said power was strong until 5000rpm then ran it flattened out all of a sudden he mentioned the cooler, I still have a stock one I’m gonna change that now I think. Also cat is 80mm narrowest point on muffler I’ll have to double check that
