I have VITZ 2004 , I got Landi Renzi CNG KIT installed couple of months back. I wasn't so happy regarding the pick and performance of car (I m not so much concerned regarding CNG consumption) So I consulted a CNG mechanic , and he did some adjustment and blocked the 90% of the air pipe connected with filter (before it was 60% blocked with tape), and reduce the gap in plugs and said it will increase the pick.
Just 1,2 days after that I got Engine malfunctioning sign blinking on my digital meter , and just to be sure I uncovered the air pipe completely, and drove my car on Patrol and that sign was gone. Since then I am driving on Patrol.
One of my friends has advised me to use Lambda. I have visited FTFS lahore , and the impression I got from there is that they r just there to rip off you ! so now I need opinion from experts here that should I go for Lambda and from where should I get in installed in Lahore?
