Actually going to RB Racing: Road. Race. Track. Custom | RB Racing word of mouth from a few locals here highly recommend and has done a few V4S in his time.I have never heard of Sydney Dyno. But a quick google showed me they have a website.
In the early days Tuneboy in Sydney was the only guy that had cracked the ECU being used for the 1199 series. Wayne (cannot recall his surname) did mine back in 2014. Back then a full Ti Akra system cost me 4K AUD. And before and after dyno with the TB software including cruise control was about 600 dollars
Biggest thing for me was almost 6 kg in weight saving and the sound.
