not really, stick with the same nitro content and you should have no problem. just be a little gentle on the first couple of tanks. If you switch nitro content it makes more stress on ur mill and a lot of heat. which is not good. This is what was told to me by a racer at my track and by alot of people. good luck. try odonnel it work s for me real good.:radio:
