Once you've bought all the big power gain parts they're good to gain 5-10 HP with. Add them to the MSD coils list.

so red your saying it's worth it ??? cause I have all bolt ons pretty much besides an intake manifold and under drive pulleys.

Greg is right about the coilpacks--but not the pulleys. Guys---get pulleys. I had the MSD coil packs on my truck a few years ago and it didn't do anything! The UD pulleys made a big difference! I get better mpgs, more volts on the alt., and more power. After I threw them on, I went for a test drive and did a 2-1 kickdown and spun them--I used to not be able to break traction on a 2-1 downkick on concrete before. But I could once the pulleys were on. RPMoutlet sells some.
