Fuel lean @4500 rpm on boost

Recommended Posts

Afternoon all,

I've been having an issue with my car whilst getting it remapped. Brought the car two weeks ago tdo5 fitted, turbo back exhaust, 270lph fuel pump and piper cross panel fliter. When getting it remapped the car was loading with fuel and at the time the boost starts the fuel leans off. 12v at fuel pump, tried 2 fprs, fuel filter wasn't blocked. It's a year 2000 car so has yellow injectors. Any help would be great, thanks.

Air/ fuel correction in row 2 is at 25% on a quick glance and without knowing anything else it looks bad, looks as tho it's trying to add 25% more fuel to the map

not sure as don't know the software or driving conditions
