Because stage 3 would be almost the same as the vtune stage 0, and the vtune stage 0 is the just the ecu upgrade and there are no problems.Have you tried contacting BSR. That's the safest bet, but for sure they won't advice it.
Might have an ill effect on the turbo.
May I ask why you want stage 3 without upgrading the other components?
Too loud and other issues?
I already have BSR stage 1, so it would be cheaper to stick with them and go to stage 3. If you go to the bsr website there is stage 3 for the 2.8T V6, 320hp 520nm torque.You have a V6. There is no stage 3 for your V6. There's only BSR Stg1 or Stg2 for the 2.8T motor. I dont think the upgrade from 1 to 3 is for the V6 engine.
Also, the BSR stage 3 doesn't need the injectors and all. They say you need a full turbo back for the stage 3. If you do an ecu tune like Nordic they recommend all that stuff to be upgraded for the full effect of the tune. I would go with the VTuner since you have the V6 anyway. It's better than BSR IMO.
Ah good stuff. I was looking at genuinesaab not BSR site. If its on the BSR site then I would do as is stated on there. If the site recommends certain things I would go with it to get the full effect. Otherwise it may not be worth the money to upgrade.I already have BSR stage 1, so it would be cheaper to stick with them and go to stage 3.

Finally got the answer. Thanks for the explanation.There are different ways to tune a car; I'm not familiar with the T8 systems in the least. The concepts are all similar, but their implementations can be different; different ways to make 'power'.
If a software tune says it requires x,y,z hardware then , unless you're fully willing to take on an exploded engine, I suggest installing x,y,z hardware. They are obviously tuning FOR their hardware, ie. exhaust flow, injector duration, FPR variants, etc. If you do not replace these components, the software will be wrong for the hardware present. Obvious things can complicate matters very quickly.
For an example, older tunes for t7 systems: One company tuned for an uprated FPR, another company just changed the injector duration higher on stock injectors, feeling that the duration was still within working limits.
Each path is valid in on its own account, however, 'mixing and matching' tune to hardware, you can see how things could get messed up pretty quickly. In this example, either too learn or too rich, depending on how you mixed and matched the software to the hardware.
View any 'mailbox tune' as a kit; IE if it says it requires the hardware, buy it. If it needs a 3" downpipe, and instead you go and make your own, I think you'll be fine. If you totally ignored the requested 3" downpipe, you're eventually going to end up with burned valves or worse.
your car, you decide.
