Sir I have a cell that has 110X110 millimetres inside the gasket,7 plates and is drawing about 5.5 amps max. I have been told this is all i can expect?? I do not know where this cell came from ,, but was told it was used on a land rover diesel. 2.4, the owner sold his car and he gave me the unit ,, to assist my fuel consumption,, I have a Mercedes 4 cyl, compressor 2.300 cc. the unit is running,, is putting the gas into the air box,, but will not get more than 5.5 amps?? your help would be welcome.
