Just curious to know if it can be used on a Stage 1 car and how does it affect fuel consumption. I suspect I have an issue with the OEM fuel pump at 5k+rpm WOT in 4th to 6th in that the OEM FP can't supply enough fuel and the cars stutters somewhat / feels out of puff. No issues in lower gears and not fussed about taking it to the dealers for them not to do anything because I have the map installed.
Advice greatly appreciated.
