Yellow box question

OK folks, I was thinking about putting a yellow box on my bike to make sure that I don't hit the 186 mph limiter when I drop my gearing down for the dragstrip. Here's the deal. I checked the instructions on the yellow box site:

http://www.blackrobotics.com/index.htm

Unfortunately, it looks like the yellow box maxes out at a 28% correction. My math tells me that I need a 34.5% correction if I want to run a 16/55 gear ratio:

16/55 = 3.4375
18/46 = 2.55555555 (stock)

3.4375/2.5555555 = 1.3451 = 34.51% higher

Is there any way to bump the yellow box up to 34.51% correction or would I just have to live with a 6.51% error?

I know that it won't hit the limiter if I enter 28%. It's just that I'm figuring that if I'm going to pony up for a Yellow box, I want it to work 100%.

I thought they made a high-ratio one as well...

Just checked the web site, guess I was wrong. Course, you could always buy two and use them in series.

I just went ahead and bought the regular one. I can live with a 6% error. Heck, I'm living with a, 17% error right now since I'm not using a yellow box right now with the 16/48 gearing. Realistically, my goal is just to not bump the 186 mph limiter. This should take care of it.
