The car is a 2004 mach one with forged internals, cobra pully swap, 2.3l whipple, 60lbs injectors, stock fuel pump, tuned to around 600hp on 93 pump gas. Owned the car for 2 days. The night of the purchase it ran great, pulled super hard, Ran just like my 03 cobra... Next day fire it up and it runs fine just driving it but anything past 1/2 throttle it wants to spit and sputter. Throwing a code for lean bank 2 sometimes. We changed all the plugs and no difference. Anyone have any ideas what else it could be? I am thinking fuel pump and or needs a new tune...picture of plugs is from bank 2
