see the thing is though, i know AVA are tuning company and probably know a damn sight more than i do, but you can only take MFI so far until it runs out of fuelling, and you also end up running too rich low down once you go past a certain point.
Still not convinced about this 2 fuel pump thing either.....its the metering head thats the limitation, not the pump

Additional to the fact 2 pumps ARE FUCKING RAPING your relay
Rick knows his stuff though so i would look into that personally
