Thanks for posting the link, I didn't see that thread, just read all 5 pages too bad it's got a couple of hate post in it.
Good work you doing man, can't wait to see the final outcome, keep us posted.
That's good to hear, those are the same issues I'm having, talked to Jeff at Whipple last week, he said this week the new revised tune was gonna be available, I wish they could do something for my headers.
What are you doing for tuning after the header install?
