As stated, Mountune 135/165 pricey. No plans for a stage 2.
Revo are great, good power 180bhp on stage 2
Bluefin, never had no problems on mine with good power delivery from standard. Changed to Mountune 6 months later.
Pumaspeed good maps, Can't comment on customer service yet but booked in for the 205+ map and billet turbo in May.
