[QUOTE="ken, post: 358823, member: 6135"] The HIOP remap interests me most of all. I guess at 140kmh under flat-out acceleration, you'd be at +6k revs in DS mode. I would think that the torque and power curves after a remap would be the same at the lower end and only move up at the higher end of the rev range, so that +140kmh observation makes sense. But would there be a loss in low end torque as JPB says? :confused:[/QUOTE] I have pre & post dyno for HIOP tune. Both power n torque graph with HIOP tune shows a higher line and the seperation is more significant from 5k rpm till 7k rpm. Low end torque is definitely not affected but just tat the benefit/advantage may not be as significant as higher RPM. in terms of fuel consumption, i feel its similar with stock n really depends on how heavy footed we are.
