ChipsWithDips,
There is nothing like actual real world testing to show what a part does. Would you like to do a comparative dyno test? Discounted for the dyno of course.
If possible, try to include LHT's as part of the comparison.
And yes, we have considered putting the side branch resonators on LTH's. That would be ideal for sure, but that will have to come after implementation of other projects in work now.
