I'm trying (without luck) to make sense of something. I have a 2011 Camaro with a Whipple supercharger. Whipple provides their own cal file which seems to work fairly well in actual use. I've been looking it over to see what they changed, and why, but I can't figure out B4001. The attached PDF shows the original stock tune on top, and the Whipple version on the bottom. The top curve makes sense to me, but the bottom one doesn't. There's no way this discontinuous curve matches the actual flow curve of the new injectors, and I was wondering if anyone knew why Whipple would use this sort of "curve"? There has to be a good reason, but it's beyond me. Any ideas?
