I would check with who ever you got the tube from and see what they have tested for, you should get a good jump in velocity even at 1000psi.

CO2 that high would be a temp of about 125 F. 85 would put you around 800psi maybe a little lower not sure without breaking out the calculator. Not sure how much you will gain with the tube. I know you get about 4 more grams of co2 with the extention.
