Hi Baldy been running a evolution chip for about 6 months now and found it to be awesome over standard,reason i used this chip was that like you i am not close to a revo dealer,cost £300 my local tuner did it on a live mapping session as apossed to rollers,the map is very progressive through out the rev range,gains of 40bhp and seen returns of 40 mpg on route to work about 40 miles round trip,hope this helps Dougie
