chrisrhondda Posted November 5, 2013 Share Posted November 5, 2013 Hi all just had a diesel express tuning box delivered plugged it all in fine with no problems, it came on setting number 3 which I didn't notice much of an improvement, it's currently on setting number 5 they go from 1-8 I was just wondering if anyone had one of these and what's the best setting to be on for the power I didn't want to just crank it up to 8 in case I cause trouble. Thanks in advance Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted November 8, 2013 Share Posted November 8, 2013 Hi Chris, Basically these settings are from 1 (standard engine running with a teeny tiny tweak) to 8 where its more map and no original behaviour!. Setting 3 tends to be a subtle tweak in favour of MPG and a tiny power gain, 5 will be a relative power increase, probably more torque than horsepower. The best thing you can do is run it at 5 for a while and then see what happens, then knock it up to 6 then keep going. You may find that 7 or 8 will cause a bit of lumpy running and duff behavior but you have to give it a go to see whats the best. Quote Link to comment Share on other sites More sharing options...
