here is the issue i had my car in to get it dynotune and my fuel is cuttin of at 4500RPM. the shop i have it at wants me to buy a kit from lethal performance instead of just switching the pump. my car is an 04 Cobra with a 3.4 whipple pushing 25 psi. I know the setup they want me to get is the best way to go but i dont have the money to drop on it. I am not totally sure what my car has in it to begin with i bought the car with most the work already done. i know it has a keene bell boost a pump but i dont know if the other pump is stock or not. Also is there a how to to change the pump anywere? I tried searching but nothing comes up
