Completely stock fuel system, is there anything I could upgrade 2 pick up some power?
Here's a list of the mods I have as far as go fast parts:
Fast Toys Ram air kit
TS&P lid
Granatelli MAF
SLP smooth bellow
Bauer ported and polished TB
LS6 intake
NGK TR-55s
Holley wires
Kooks 1 3/4 race long tube headers
custom true duals
ASP underdrive crank pulley
Meziere electric water pump
C2 cam (224/.581/112) Plan on going bigger soon.
Everything that pertains to the fuel system has never been touched and I was wondering if anything could be upgraded to pick up some more power or to make the car run better. I dont know what all can be upgraded, but if theres anything out there that can help me out, please let me know. Thanks a lot.
By the way, I havent had the car on the dyno in a while and Ive made several changes since then, but back when it was dynoed it was around 480-485 hp to the motor. Now its probably around 500 hp to the motor. I dont know what it puts down though, hopefully soon I will know. If there is any other info that you need, please let me know. Thanks.

So the pump, fuel injectors, fuel rails, etc. is all fine for my mods and power??? I figured something was almost maxed out, but I wouldnt know because Im no expert when it comes to the fueling system. How much power does the stock fuel system handle? Thanks.

Stock injectors (28.8lb/hr ones) around 420rwhp. Stock pump about the same. Stock rails around 550 rwhp without an add-on regulator/return line. These are conservative numbers as folks have exceeded these.

So shouldnt I consider upgrading the injectors and pump? I dont know what the car puts down anymore because I havent had it on the dyno lately, but back when it was a 6 speed and many mods ago, it put down 417 rwhp and 388 rwtq. Ive done every bolt-on that I know of and I wanted to see if there was anything that I could upgrade in the fuel system that might give me some more power. Would I see any gains right now if I was to change the pump, the injectors, or both? Thanks.

If your factory pump is healthy you will be safe to about 400RWHP.

How do I know if my pump is healthy or not? Back when my car was a 6 speed, it put down 417 rwhp 388 rwtq. So wouldnt that mean that my pump is over worked or needs to be upgraded? Im sure it still puts 400+ even though its an auto. now because I have squeeze a little more power out of it since then.

BlackBeaSST, if your airfuel ratio is fine (check it on a rear wheel dyno), then upgrading the fuel system will gain ZERO hp. If you run out of pump,injectors,etc, then you will go lean and will benefit from a component upgrade. With your mods your fine. Step up to a supercharger, N2O or more cubes, then upgrade the system.
