Cain beat me to it! Many thanks Cain....saved me typing!!
There's no massive increase in performance, just that it feels more lively and 5th gear is far more useable. The only down side I felt was that first gear became very short but not really an issue. I was surprised that fuel consumption didn't really change...the engine is running more in the sweet spot most of the time and not slogging in 5th in particular.
If I were to start over again with the Sigma 4/4, I'd forgo the throttle bodies and just fit the comp axle, full sports exhaust and a decent filter set up, similar to Cains and follow up with a remap.
