Not very familiar with this lark lads so enlighten me. After the missus instructed me to go for a diesel A3 weve spotted the ideal spec, but its not a DPF 170. After checking out Star Performance (theyve fitted Cruise on a few of my A3s in the past) they say they can use software to increase the 140 to 180bhp. http://www.starperformance.co.uk/audi.htm Im not savvy with this what does it involve and is the end result a pure 180bhp, like they say? Id appreciate at any thoughts/advice - !
