Nope. I disagree. I even talked with Msd about this.
Ive been running a MSD Soft touch with my mp Chrome box for about 3 years or so.
works perfect. Both boxes were bought USED in 2004.
you may have had it wired incorrectly ?
As long as your not ramming the crap out of the limiter its not going to affect it. I shift at 5800 or so and my chip is at 6700 just for safety.
It worked perfect when i blew up my 8.75 rear end . saved my engine from seeing 9000 rpm's
Not only that , but everyone ive ever talked to that went from a chrome or gold box to a MSD 6al/7al , gained NOTHING.
