you need new ones....you have a 2000...they only have 26 lbers from the factory...Try a set of FAST 36lbers....same injectors that came in the GM ASA cars so you KNOW the specs to input in your Injector tables or your tune....Or a set of SVO 30s...lots of guys have success with those
I would grab some 36# injectors or higher. I would not go higher then 42# injectors unless you plan on pushing past 500RWHP.
I have been around and around with injectors.... I would buy some more and truthfully I don't know why they gave our cars such small injectors

We have several options in the 42lb variety.
We have New Bosch Design II's (old style SVO) for $49.95 each
We have new Lucas 42lb for $42.95 each
We have our rebuild Bosch Design II's for $239.95 for the set of 8
And our rebuilt 42lb Bosch Design III's for $239 for the set of 8 (I recommend these)
42lb is a lot of injector for a V8. what kind of CHP do you have?

What size injectors do you recommend ? My engine is built to handle 500hp but I don't have the heads or intake ported yet. It should not be hard to exceed at least 400hp...or am I wrong ?
Upgrade your entire fuel system. I would start with the fuel pump. Stock won't hang on much past 5500 RPM's with the stock system. If your making power, get a better fuel pump. Good idea to do that and the 36# injectors.
I agree

I went the "cheap" route and dont regret it ONE BIT. i bought some low mile used 2003/4 Cobra injectors which are 39#ers. I then bought the adapters from Casper and it cost me a total of under $300... I dont know, you tell me.. i get enough fuel w/ a racetronix kit and 39#ers
