Yes defintely will affect fuel consumption. Higher RPM, higher amount of fuel burnt. However for every car there is a sweet spot of RPM vs speed.. Where the speed and rpm combined gives u the best economy. What i have tried and tested so far is 3200rpm @ 4th gear (auto box) speed 115-120km/h.. The best fuel economy i have seen in my car so far. Going at 2k rpm @4th gear speed around 80km/h is not that economical actually. As the drag is still very minimum to create a huge effect on FC..

Why i would encourage Cam-tak-pro and Campro IAFM engine users is that they maintain at least 2.8k rpm on their engine for max power vs FC ratio. This is due to the slightly higher amount of overlap between the exhaust valve closing after the intake valve starts opening and the lack of backpressure from the extractor till the downpipe, which is good for high engine RPM as the pressure of combusted air exiting will pull the fresh A/F into the chamber, inducing more richer mix of unburnt fuel into the chamber = more power. However at low engine RPM this will cause unnecessary wastage of unburnt A/F mixture due to excess unburnt A/F mixture being drawn into and out of the combustion chamber and low back pressure from the extractor side which prevents this from happening.
