I'm looking for some feedback on the chassis dyno process.

I took my ITC to the dyno, they hooked it up, warmed the engine a bit, got it up to 3rd gear and floored it unitl it hit 6,500 rpm, then shut it down. Then they tell me I'm off the chart on the lean side so we increased the secondary fuel jets on the weber. We repeated this a couple of times until horsepower and torque stopped increasing.

Does this make sense? Is this going to relate to running WOT at Daytona for a mile long stretch?
