The stock 1290SA is very well fuelled, but after adding a BOS desert fox muffler I got the usual popping.
I thought if I'm going to do anything about it I may as well address the whole system, so I added the fantastic Rottweiler intake and velocity stacks, a power commander V, dual auto tune, SAS removal, and the Arrow headers with the cat (I'm in Europe where they can sometimes check theses things).
It went together well, and the beast growled at me as soon as I hit the starter.
The power map maximises the value of the improved air flow from the intake system, and set me up really well to start the auto tune (which I haven't needed to use yet).
The manufacturing quality and industrial design of the intake baseplate, and the tuned velocity stacks, is exceptional- vastly superior to the OEM.
This is a unique performance mod, in that it gives you not only the improved performance you're after, but also the peace of mind that your bike is actually better off with it.
Most impressive is the after sales help provided by Chris. I had a few oddball questions that he graciously answered quickly, clearly and concisely. It's no overstatement to say that in my 35 years of motorcycling I haven't had better after sales service.
