That'll hurt even a N/A motor, let alone a boosted motor. MSD's limiter drops sparks to cylinders randomly (hence the "soft touch" name). Oh yeah...the 6A was a breeze to hook up with an MSD distributor.

They were probably thinking emmissions and really hot catalytic converters if unburned fuel was forced into the exhaust, besides you need fuel to create a really lean fuel mixture. Cut off an injector and theres no fuel to create an excessively lean A/F ratio. Through a wet nitrous setup into the mix and we'll thats another story (kaboom)
