i just installed a fass 150 along with super b turbo and ats 2 piece manifold. when im just setting in park i can gradually increase rpms and they jump around alot especially when i let off. they jump down in increments. anyone know what this might be. i had a predator programer on it so i took it off and it doesnt do it as bad. i also i have a small leak where the fuel line goes to the pump on the motor. is this caused by the other line just being there?

thanks for the help!
