Before chucking the chrome box..
Be sure to check your ground connections for the box closely, these need to be tite & kleen..

Just my $0.02...

Some real good advice here ^.. I had a chrome one do that and wasnt grounded well.. also burnt a couple of chrome boxes up using an accell super coil. You might want to consider a stock oe black box, mine never misses a beat, but I dont go past 6700.
