1st gear pull is not going to have as much boost as a 5th gear pull.
In general, the turbo starts to make positive pressure in the 2,500RPM range.
The twin scroll acutator kicks in at around 2,800RPM.
It should be making full boost by 4kRPM.
S5 turbo can make positive boost as low as 2,000RPM.
I'd be surprised if it does.
The "Rev" spec exhaust is supposed to be proprietary, so it doesn't match with any of the stock "breaks".

Yeah, the ghetto catback was some knockoff N1's.
All of my boost woes happened in any gear at full load. I didn't even start seeing positive pressure until 3800 or above (using a mechanical boost gauge). I do have a dyno from a baseline pull I did and it is a little obvious when you are looking at it. Hopefully this S5 turbo takes care of the issue. Positive pressure in the 2k range would make my year!!!
On the exhaust.... damn. Guess I am gonna have to get the whole thing then
