Depends on the setup, but depending on how big you go with the cam it would be recommended

 

well, its always going to be my daily driver and i am still spinning my wheels learning about cams.... seems like a lot to nail down, all i know is, i want more lower end power without losing the ability to pass people on the freeway when needs be....

but at the end of the day i am looking for as much power as i can squeeze out of my truck without compramising its daily drivability...

 

If you do decide to get injectors, go to the classifieds page. I picked up some 42# Marine injectors for 230. They pop right in! If you can get a good tune, you wouldnt beleive the difference from stock.

 

Yeah I will get a retune from my man Wheatley. The reason I ask is because Ive been getting dct's and from what I read most likely its the injectors and if not its the cats....

 

KB I look for FIC injectors on LS1tech and I cant find them...If you have any info that would be great I would go that route...Thanks

 

Sorry I found them....I will call them first thing in the morning...Thanks Guys

 

I maxed out my stock injecotors on a cam only LQ9
42's are safe but save yourself the hassel if you go FI get the 60's

 

i got some shorty 60s from SRT10Killer off here.

 

What size injectors are in a 4.8 2003? And at 58 lbs of pressure are they maxed out ?

 

After all of that you'll need injectors.
