Its stock that's why we use a fci intake, dasa pipe, and programer and it will really open it up. As for the fuel pump it should prime for aprox. 10-15 seconds.

Fuel pump primes for 3~5 seconds to 43 psi...

As for extra performance, Get a FCI, LTR tube or a velocity intake add stg 2 or 3 cams or KX 06~08 OEM cams....and it will increase 30~50 % over stock 32 horse power...New.

Check first the pump relay for being stuck, swap it with another to test...

Can you test the fuel pressure for a bad pressure regulator 43 psi above 1800 RPM/idling....
