Oh, and to the OP...sorry not trying to jack your thread.
I have to agree that adding LT headers is really all you need to get the most out of the IPF SC system. You'll be making incredible power...and it would be easier to have them installed before or during the SC install.
Otherwise, if you want to get the most out of that power, proper suspension should be your next focus, and if you take her to the 1/4 mile track, you'll want some good sticky tires. Preferable a DR on a lighter 18" or smaller riim will get you the best traction by far! This would likely have the added benefit of similating a lower gear ratio as well.
Good luck on your awesome purchase!
