MSD Ignition, any experience?
I've got an '05 Sierra, 5.3L and I'm looking for the next performance upgrade. I'm curious how much a multiple-spark ignition system would help. Is the money better spent at the coil packs? (650 to replace all 8) MSD's -6A and Blaster Ignition Boxes are cheaper upgrades but are they worth it? Any thoughts?2005 Sierra 1500 Z71 Crew Cab
