I don't really use the Dynoject conversions either, but when you compare 2 cars on the same equipment, you should see the differences. I'm concerned that a stock CS had about the increase in hp you'd see from a stock Competition. Regardless of the equipment, all things the same, a stage 1 tuned Competition should be higher than a stock CS. Especially given Carbahn gives a projected 100+ hp increase.
