So i went to get my e85 tune, and the car is getting lean up top @6300 rpms. Is there a direct replacement pump to my Fore Dual GT pump Hat? Im only looking to make 700-750 with my setup, i might add a little more boost (19 psi as of now) but the pumps are limiting me for now, and i hate to buy a new fuel system if i can replace the GT pumps and call it a day. Any help is appreciated. Thanks
