Hey guys,

I have a s4 T2...stock block, turbo, and ecu. Mods are TB, TID, RB 3" dp w/ hks single side 3" from dp, 680cc secondarys, FCD, 3rd gen fuel pump, FPR, and pump has been rewired. Im running about 9-13lbs of boost and running rich.
My questions are i have a MSD DIS-2 module, will i see/feel a significant increase if i install it? Is there anything else needed to install it, will it hurt anything, will i need to switch plugs if so what type. Or is the stock setup good enough for what i have and hold off installing for when i do build the motor up with all the bells and whistles. Thnx guys.
