speed density 
Kind of new at this,I'am transplanting a LT4 from a 1996 corvette into a old hot rod .there isn't enough room for a MAF sensor so I'am running the engine I guess in speed density.It is not street ready yet, But I'am confuzed. If I have herd right just by not plugging in the maf sensor the ecm will run in speed density. can anyone explain in simple language if this is right and will i need to have it tuned.????? thank's

Yes, without the MAF functioning, it will default to speed density. Though, it is real easy for a tuner to force it to speed density all the time, tune it and you not have to worry about it.
