it isnt rich! its spot on to the boost i run,and my car sucks air in more than most rs turbos due to my mods so i have to match the air to fuel, like someone said earlier the KE can flow enough fuel up 240 bhp with the right mods, i also have a higher pressure pump aswell....

cars may appear rich on a dodgy rolling road tune, get it wideband lambda tested going down the road with a tuner like Stu's place in blackpool or APT in Norwich which use the latest equipment under proper conditions and u will see!.

Most tuners will put a bit more fuel in on top boost anyway.
