Bigger inj DO help! I know there is a lot of debate over whether or not you "need" bigger injectors for anything under 500hp. Well, let me add some real data to the debate. I am right at that number (490) and I just swapped out my stock 26.6lb inj for some 30s (= 34lbs for our psi rating) and I picked back up the 10 or so of the 15hp I lost after I installed my 9" Moser rearend.
So for my car anyway, my inj were maxed out & I needed bigger ones. To me this validates the injector worksheets I've posted links to here a few times. So while your stock inj CAN work, you MIGHT be leaving hp on the table by using them after a certain point. And it's under 500hp, at least in a 2000 TA.
No flame war requested, just trying to add real data to the theories.

I totally agree with you. I'm also crusing in the HP range you are and I too have realized a few more ponies by putting in the 30#'s. I found out that on the Dyno we couldn't get the AF to go below a certian point until we put in the bigger injectors.
How did you tune for these 30s using HP tuners? I just bought a set of svo injectors and will replace my 99' 26pounders on Monday.
Any suggestions for taking the old rail off? I wish I had done this when I swapped in my ls6 intake.

on 02 models like mine dont i already have bigger injectors like 28#'s or something?? if that is tru, im prolly wont replace my injectors until i get up around 500..
im just asking cuz im about to do a cam install, and am hoping for around 400... think my 02 injectors will be okay?
