VW Golf MK5 GTI Stage 1 ECU tune review
Thankyou John at Bluefin, the stage 1 tune on my Mk5 GTI feels like how it should of come from the manufacturer as standard, big increase in power but completely safe and inline with the cars abilities. I wish I did this earlier, I was hesitant because about 5 years ago I spent $1500 on another big "3 letter" tune on my Tiguan and that was a big disappointment, this bluefin tune is less then half that price and feels twice as good!!
