Are you running the stock injectors with that plenum & TB? Does it work OK or is an upgrade recommended?

[/align][/align]A 4.6L Mustang is not a Civic or some other deliberately hobbled by the manufacturer econobox, the stock injectors are fine with nearly any so-called "bolt-on" mods*; as is the OEM MAF--particularly on the '01-1/2/'02 models with the 21# (pink) injectors...[/align][/align]-------------------------[/align]* - Technically turbos, superchargers, and even cams are "bolted on", I.e. you can do it with the engine in the car and without pulling the lon block apart; however convention defines "bolt-on" as non-FI, and stuff that doesn't require pulling the valve covers...[/align]

 

what would u have to do before you upgraded injectors?

 

Add some form of forced induction, or some serious engine work--bore/stroke/pistons/cams/heads...[/align]

 

all the abover or just one of the bore/stroke/pistons/cams/heads

 

The stock injectors will make it to 260 to 275 rwHP (assuming 0.5 #/hr per HP, and pushing them to 85% duty cycle and/or higher fuel pressure); the stock MAF is good to 300HP or so...
