I have and stage two, was going to get them to do stage 1 revo demo before I had the hardware for stage 2 fitted, they advised me the trial map is not a true representation of the full version, the trial is deliberately boosty down low to make it feel quicker, so I would just get a full map by a reputable company, you should see 45 bhp gain, be warned you will soon want stage 2 lol !
