so what's the theory behind that ... Obviously its getting more air pressure .. but what is it effecting??

Is it affecting the MAF?? ;)

It affects the diaphram. I don't know exactly what it does but has something to do with it changing from rich to lean with the forced induction. The maf as far as i know isnt used on the gas in this system.

I wish I could quote the terms, but its been a while. most gas systems are set to run rich, so you don't come back every day and complain when the weather changes, beause a convertor is a regulator and reiles on atmospheric pressure to operate correctly. I found I could get amazing ks to the tank by adjusting the mixture and reaction screws to the conditons of the day. This should be easy to do with just your fingers if you convertor is easy to get to. Storms= low pressure, nice day most likely=high. I strongly suggest that you do some reaserch on your convertor, theres a few types, and learn to adjust it yourself. You can't run lean on gas, it just won't go, or will have no power. So there is nothing stopping one from playing with the system. But you can run rich. Once you master the settings on your convertor, you won't need to see a mechanic again, and you will save on gas, you will spend a little more time under the bonnet as the weather changes. Disconnect that balance hose and see what happens.

Yeh the mechanic has showed me how to adjust it so i will play around with it. Might stuff it up but thats part of the fun:p

I would be checking the condition of your air filter, the filter is designed to take air from the front where the trumpet snout was. Your filter would need to be rotated and cleaned regularly as you have the air directed at one small area of the filter. I will try and post a pic of how I changed mine from your setup to breathing as it was designed to, the change made a difference to performance and filters lasted a lot longer, Regards Frank.

Yeh this was a concern but it was the easiest for me with so little room. I have a K&N washable filter installed so rotation and washing will overcome the cons of this set up. I would still like to see some photos of yours to compare as it maybe worth changing it but will wait and see.

If I had LPG like yours I would be getting rid of that enormous Washer Bottle, which would give you plenty of room.
K&N filters will allow up to 38% more particles through compared to the OEM filter. Also the oil medium in the K&N filter can contaminate the Hotwires, I ruined a new engine in 15000klms using a K&N filter which dusted the engine, there is plenty of research available on this Forum which will give you info on these filters, if you go to Gallery and the Albums, Tank, you will see in pics how I did mine, Regards Frank.
