Im a steady 19-20mpg in dynamic and man from mostly school runs and 10 miles to work with the occasional blast, i was 17-18mpg before i got it mapped. asda fuel all the time Dont trust the range i can easily loose 10miles off it on the school run these things dont like short trips @Tashfeen haha i hear the tenner thing my mrs regularly heads out with 20miles on the range and i need to warn her to get fuel before she comes home otherwise its a jerry can job ( although iv done the 10miles home from work with 0 range on the clock
your not wrong.. looking around 70bhp increase and + 10% fuel savings for this engine , have to tried a Hydrogen engine clean. I normally see a few mpg from this alone
yeah stage 1 just now with zip tunning and its never missed a beat, never hand an engine clean my right foot makes sure nothing gets a chance to build up
