100 pound loss = how much HP gain???

That's why when I see any combination sorted out to where the ET matches the MPH I'm impressed. It's hard to do. And the quicker you go, the smaller the flaw that will expose itself, and is usually harder to fix.
EXACTLY !! And even MORE impressive when it's done in a true street car. Drag cars with 5200 converters, 4.88s and slicks makes it easier. Of all the cars I've ever owned, my current Duster is the ONLY car I've ever owned to have the ET match the MPH, and they've all been street cars.
