Basically I was wondering of changing to 42 lb injectors would with a new bigger Mass air flow meter, tuned, would hurt to be on my car now? Would it flood it? or would the current program keep it from flooding my car rich? I'm doing the big pnp pi head swap next year, and solid block, and probably gonna play with a big shot of nitrious. So I know I need around 42 lbs because i'm expecting 550 hp +. So changing MAF and 42 lb injectors, tuned now with my current mods is that a "Big Mistake?"
