Jb4!! Help please

Hey guys, I just installed my jb4 with a flex fuel system. The flex fuel was already on the chip but I ran out of time and diddent connect the fuel rail sensors. So I turn my car on and at map 0 (stock) it feels way noticibky slower than the normal stock. I ran a stock n55 and he blew by me. What can this be? The fuel sensors?
