5.3 Coil Pack Upgrade and Wires = ???HP

How much potential gain is there for my 2000 5.3 Sierra if I do a MSD Coil Pack and Wires upgrade?? I do plan on performing a BB Custom tune after this bolt on as well...Thanks to all that comment!

2hp from the plugwires and coil pack. i would never suggest changing out the coilpacks unless you are having a problem with the stock ones

maybe 10hp from the tune

you are about as likely to gain hp from the coil packs as you are buying a keg of beer, so I suggest plan B

MSD coil packs have given many people problems. A vette guy I hang with took his all off after 2 failed..... They look good but OEM is MUCH better.......
