I remember Tim Powell's old boat running before and after the DBR upgrade. There may have been some mid-range improvements but his holeshot and top end were no better from what I saw, and from what his GPS recorded. That was a disappointment to him and me. He was at 98.8 a couple of trips before he had the DBR upgrade but never got back to that speed again. Close, but not what one would expect. But, it (his numbers) saved me from going DBR. But your's did great. Just goes to show there is no absolutes in all this craziness called fast boating.
