I just dyno'd at HPF in Portland and my first couple of pulls I had a big dip at 4000 rpm. We ended up putting boxes of sand in the trunk, @ 250 lbs. Went from 425 whp to 440 whp. Even then I had a small 10 whp dip when my turbos spooled, but we didn't have any more boxes of sand for weight and I wasn't about to sit in the trunk to get another pull.
