Does anyone here run their 790 with a linkpipe and no mapping. I'm going to fit mine but the Akra mapping is not available yet, at least not here in Belgium. I read somewhere that it would not be necessary with a long exhaust and a midpipe with enough backpressure. The Aroww midpipe seems to be bigger and more expencive than all the others so I guess there is some kind of backpressure system integrated but not sure...
