well guys....found a cheaper alternative, 350 cheaper. I got it dyno'd before and after. completely stock at 144.5rwkw to 169.0rwkw. Very happy with the result, and now on my way to 200rwkw.

Im not an expert but i think it has to do with back pressure so i was told, from experience with my car i had a 3.5" exhaust with a 5" tip hks cannon, the car makes 330 rwkw and it did have lag. The turbo didnt cut in til 4000rpm.

Changed it to a 3" pipe and smaller cannon, it feels more responsive quieter and the turbo cuts in at 3500rpm.

wrong wrong wrong

Turbo cars = bigger exhaust the better

There was something else wrong with your setup, it wasnt exhaust related, unless said exhaust had poor bends etc.

Hence im going twin ~2.75" for my setup and only after 300-330rwkw

let's just say i removed the cat but still had the cannon out the back (making the car seem normal and safe) but in true fact had a GAP in the exhaust so all id have was an aftermarket dump/front pipe then an empty space then the rest of the exhaust.. would i have extreme spooling and extreme kw increase?.. (apart from the loud noise)

Do you mean putting a replacement pipe in where the cat was?

there will be a minor gain possibly

ok let me re-explain... complete exhaust system is taken off... all that is left is the dump pipe and front pipe safely bolted on the bottom of the car

The car will be so illegal it wouldnt be funny.

Your NOT allowed to run a car with an exhaust that finishes that soon, it has to be past the rear pillar or whatever to pass the most basic exhaust requirements

Plus it will be that loud you wont get far without half the neighbourhood reporting you.

So dont expect "extreme spool, power increase"... expect the "extreme ass kick" local authorities will give you for being stupid

trust me... in perth we go for car cruizes all night and no1 looks 2wice to try an " extreme ass kick " on us.. im just curious if it would have an overall performance increase

i've been to perth actually and i saw a different view :(

Funny eh?

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
