I have this exact issue! which is why yes I have a remote line, but still use co2 instead, as the fps on air is rubbish compared to co2, just need to be careful in terms of first strikes, as the first shot from a fresh co2 will be rather high.One not of caution regarding the TiPX and remote air - a lot of people have reported being unable to chrono above 250fps when using that setup. The gun with chrono in the 280 region with 12g CO2, but on remote refuses to go above 250, regardless of the remote line used, or tank reg. I had exactly this problem and after searching for a fix found it was widespread.
