I noticed just this week when running around 70 kph that my car seems to have a difficult time at that speed. Parang nawala yung pick-up niya unlike the time when I was using gas. I was not able to notice this before because I seldom go higher than 80 kph in metro traffic conditions. Is this normal or there's something I need to check or need for retuning?

Also, do I need to use gas before and after using LPG? I try to run on gas for a few minutes on start up and switch to LPG. Before turning the engine off, I also try to run it on gas for a few minutes too. Am I doing this correctly or do I need to change the steps?

My kit's running condition is fine at low speeds and rpms. FC is also acceptable at around 9.5 km/li on LPG as compared to 11 km/li on gas. I think I will still need to get more samples of my FC to get a more accurate reading since I've had only a number of fill-ups. My kit is an emulator on a 98 Corolla GLi.
