LtNoogie: you are correct that your injectors are to big. Our stock injectors are in the 190-200cc range, TC injectors are in the 350-370cc. The most you can go up in injector size without driving the computer crazy is 20%. That would be in the 230-240cc range. I feel that by adjusting your fuel pressure to compensate for running too big of an injector will not help. It would be better and less expensive to buy the correct injectors than converting to a returnless fuel system.
