Rediculous furl consumption issue

[Tobymaloo]

Hey guys

I recently bought a vy ss 6 speed, and its essentially stock with headers/exhaust , ramjet cai and a tune. I also have a vu maloo 6 speed cammed.

The issue with the vy is its using about 21/lph Nanny driving with the odd bit of fun. Ive had it on the dyno to check tune and its lean running around 14-15afr all times, but using rediculous amounts of fuel. All 02/maf/air intake sensors looked to be working as they should. My cammed vu sits around 17 lph with hard driving. It baffled my maye with the dyno and dont know how if its always lean, its using so much fuel? Any ideas would be much qppreciated

Leaky fuel injector or injectors perhaps? Definitely wouldn‘t hurt to remove them and get them properly cleaned also how old is the fuel filter? Replace it if unknown it’s cheap and easy enough to do
