A way to remove lookup tables and calculate those values?

I tried using sin/cos calculations and it resulted in the same speed or maybe slightly slower. I am only using 9600 baud out. This may be where im hanging up. I didnt figure that it would be the bottleneck in the operation. The next test will be to bump up the baud rate and see what happens.

EDIT: I changed over to the USART and set it up at 19200 and sure enough its displaying the gauge points twice as fast. Now, I have to tie the 2 USART transmit pins together because I have to initiate communication with the GPU at 9600 baud and then change the baud rate. I need to change the baud rate for one USART on the fly and re-DEFINE-ing the baud rate doesnt seem to work.
