I often come across customers that are only interested in peak BHP, we often lose these customers because cheap amateur tuners i.e we 'r' remaps.com down the road in their mobile tuning van promise more horespowers
You hear tuners talikng about 'area under the curve and average power gains' and I think this illustrates this perfectly.
Today I was tuning a BMW 325d which was a perfect example of why peak BHP numbers are just pub talk. I flashed on a stage 1 test map (pink line in this graph below) and although the peak power was good, the entire mid range and low torque/power was missing something.... I had missed the in gear torque limiter maps
so back to the map editing software and 30 mins later we had found the missing power and torque (red line). So although both maps made within 5bhp of eachother, they would have been very very different on the road. Another big reason why dyno tuning is so important during software mapping.
