First thing you want to do is to buy a K&N filter, I ahve one in mine and it made a noticeable difference. Second thing change ALL the fluids to synthetic, engine, tanny and diff. The last thing if this is not aenough is to put a chip in. There is a company that makes a chip and takes the power to 199 and torque to 229. That is my next step and should make a big diffence. The 201hp engines made less torque, I have driven both and you might not like the loss of response and lower off the line speed with the 201hp cams. The chip will give you almost the saem power and much more torque. If you out the K&N gfilter in you will pick up about 10hp as well so without cams you will be better of with just the filter, about the same hp but more torque and better response. I have driven a 201hp 960, I have a S90 (181 plus filter about 190) and a new S80 (194) and found the S90 to have the best pick up off the line.
