Not sure that it helps you since I don't have my dyno to post, but I LOVE my 212/218 .550 112 from TSP.

It and a couple other mods got my truck to 302whp. But the real plus was the liveliness it has from idle compared to the LS9 cam that was in it before

I'd go with the converter skewing the graph. I have the same cam I've never dyno'd it but I can tell you it was a complete dog before 3k without a stall on a 5.3 I mean as useful as **** on a boar hog. I'm no expert but on my logs it shows the most cylinder airmass around 4600 runs pretty well though now I've got a 3200 stall it could honestly benefit from more stall but I still use it as a truck is intended so I went lower.

I'm very happy with the TSP stage 2 in my truck. Woke it right up. Didn't lose any low end at all, it actually gained a bit. But over 3000rpm she really comes alive right to 6200rpm. Still have the stock stall, wouldn't mind trying a 2800-3000 stall.
