CNG is pain in the ................... !!!!!!!!!!!

Hi all and specially @Aryaan
i want to know the experience of guys who installed CNG in EFI cars(complete EFI kit with emulators and advancers)(non factory fitted). CNG cars dont have nuts and bolts like in carby cars which u can mess around to adjust the mixture or iddling. in EFI cars everything is monitored electronically(mixture and iddling).
Problem # 1 , Iddling,.... car stalls on red lights. Car stalls with AC. and sometimes when u slow it down.
Problem # 2, Got CNG fixed in a Santro Exec, it blew off the Air cleaner box twice(with a patakha!!!)....what the..... is that? sold the kit and then the car : D but why was it happening? Talked with a spare part dealer.He said Air cleaner box ki bauhat demand hai specially in XLI,same problem?Why?
I have tried all adjustments for iddling,even messed around with the accelerator wire!!!...this suxs

hello...
yaar strange to listen that air filter box blows twice....yaar i can't listen that problem ....listen and solve many cng problems but not like that...it maybe some wrong installation or incorrect seetings......as we come to stalling problem so yaar its caused due to mostly 90% Incorrect Air/Fuel Mixture....that causes the problem of stalling at signals or when u turn on A/C....i personally tune my car myself and reduce gaps to 0.6mm from 0.8MM...for CNG....but i think Efi cars have advancer so it can manage on 0.8mm but u can do if u face any difficulty in hard starting.....
the air filter thing i can't actually said....it maybe caused by cheap using of material or maybe some air pressure...do u notice any thing when it blows out....means air leaking or high air flow.....????
Thanxx
