Ginz LS1

I have a 02 camaro with some good mods on the car but I cant get it out of 13s. I have found the car is running really really rich and we are trying to lean it out. The symptoms seem to be a fuel pressure regulator but the more and more i look i can only find a thing called a damper. Here is what is going on
Cold Starts smells like fuel (strong), dies out in reverse, loses power during high RPMs.

We did a car dyno at FLP at with all the mods on it it only pushed out 321.2 HP and 308.4 TQ which sounds like a stock Z, so this is what is bothering us. We are trying to find someway why this car is so ****ing slow.

does anyone know how to lean out this car and possible figure out why this car is running like this. could he need just a tune up ?

Are you sure that ls1 cars have fuel pressure regulator??? I Am 100% lt1 guy and know nothing about ls1 but I am pretty sure they don’t have one

What mods? If it was at FLP, they should have scanned it while it was there.
