Never got a straight answer. Does my Marc H chip need reworked to support this upgrade?

Do you have a mail order headers+exhaust chip from Marc? If so you would probably be okay as I'm sure Marc adds a little extra fuel on his mail order stuff to be safe. Marc would most likely advise you to send him the chip in order to add a bit more fuel - just to keep that extra margin of safety.

Steve, one thing that may have been unclear but these IH's have no secondary butterflies so unless you've already removed yours a retune will be needed.

Congrats on taking the leap, was eying these myself but have to wait for post-season to consider this level of project.

Cheers,

Just an respectful FYI, Secondary port throttles (butterflies) are located in the cylinder head, not the injector housings

Thanks Jerry, I was concerned I'd have to mess with the secondaries.
