2cents I'll throw my 2 cents in. i run a 10+ box on my whipple charged chevy. 557 ci and 45 lbs of boost and have had zero problems with reliability. I have never run a mag on this combo, so I'm not going to swear that it wouldn't make more power. I will say this, there are 2 camps on this. Most that are in the "mag camp" have never run anything but a mag. There's just a mind set that blown motors should run a mag. John Scialpi, pro-mod engines builder ran Crane hi-8 and switched to a mag 44 when they restricted pro-mods to 20% overdrive because it made 12 lbs more torque on the dyno. i wne t with the 10+ box originally becasue their were more timing control options available. Now that MSD has come up with the new mag controllers and you can even use the digital 7 to fire the mag w/ slew rate rev limiter, not sure which way I would go, except to save $1500-2000 by using the 10+.
