That dyno looks way wrong on the low end, even without the secondaries. My dyno looked like a muffin top... nice and fat with tons of midrange... I don't have a dyno run with the 3L UIM on, but the low end and top end are much improved over the stock 2.5L... Even without tuning.
No dyno graph scanned in, but since I have it here at work, I made a quick .xls file to graph mine out from SZ02.
