Also what manifold are you running. I have brought this up multiple times and it is always a fight but i would seriously think about getting a Twin Scroll Manifold to get the problem of gases running back into the exhaust ports. ALso what gas were you running? What kind of timing are you running on pump and on race along with boost for both? PM me and we can talk more private but we can compare some stuff since we have allot of the same mods just different turbo. Also can you send a log from the Motec so i can see what it looks like? Are you running your knock table to retard or richen the fuel when it sees a certain amount of knock? Honestly with your setup you need to get .82 housing at least with that turbo or go with the 3037 or the 35/40 with a .63. But i would be very interested in seeing all these variables. Also you are running the tomei 260 with 11.5 of lift right so there shouldnt be any worry of overlap with the bigger turbo? Talk to you soon!!! We will get it figured out!

I also wanted to add then when your turbo surges it does create a sound that could be mistaken for knock. Unlikly but i guess that it could happen if it was loud enough. I wouldnt go with the 1.06 housing at most i would stick with the .82. You did get rid of your cat right? What exhaust are you running after the ATP downpipe?

To start with a big thanks for all the response and concern, this is really killing me since I have a pretty large amount of $$$ in to my engine by now and a simple test today showed that my car wont even beat my friends EVO VI with a stock 10.5 ti turbo We tried a couple of pulls in 3rd gear at 4k and he was actually pulling away slightly up to about 5k where I started to gain ever so slightly up to 7k. He is running stock turbo but otherwise a similar setup as mine except he also runs stock cams.
Az3ar here is my full spec:
MoTeC M48 stand alone ECU
ATP Garrett GT3071R .63 a/r
ATP 3" stainless down pipe
ATP 4" custom suction pipe
ATP lower intercooler pipe
3” cat delete pipe
Tial 38mm external wastegate
Eagle forged H-profile conrods
Ross forged pistons 8.5:1
AMS 780cc injectors
Tomei 260 11,5mm IN/EX camshafts
Tomei adjustable cam gears
Tomei valve springs
HKS Super Sequential blow off valve
HKS super power flow air filter
HKS Hiper 3" exhaust system
Custom made high flow stainless exhaust manifold
Sytec 255l high capacity fuel pump
MAP sensor MAF removed
Az3ar, could you do a small test for me, try a run in 4th gear from 4000rpms to 7000rpms, try it a couple of times and see what times you get. My car did that in about 9sec before the turbo kit, now it does it in around 7sec but now we also know that a car with a stock turbo could do it about as fast if properly tuned.
I have very little information on the tune it self and I have no possibility to connect to my ECU to pull any logs at this point. The company who tuned my car is called Trollspeed and they mainly do rally and rally cross cars and some of them are EVOs, their most famous car is probably their Pikes Peak Saab 9-3, don’t know if anybody has heard of it? Anyway they have tons of experience in tuning turbo cars and they had never encountered anything like this problem. A very sad thing is that they are some 400km (250miles) away from me and yesterday was in the $1,300 range for 9 hours of work plus gas not to forget getting up 3:20 in the morning and back home 12:00 in the night
I tuned on 98oct RON pump gas and no race gas at all. I think 98 RON is about 93 ANI or what you call your grading.
I actually ordered the .82 turbine but ATP sent the .63 by mistake. They said they would send me the .82 if the .63 didn’t work out. I will give ATP a call now and listen what they have to say about all this.
I have attached a couple of pics of my manifold. It’s custom made and maybe not a perfect design but it should be better than stock at least.

But what exhaust manifold is that?

I talked to ATP last night and they were going to discuss this and get back to me.
