Guys i am totally confused about GLi and GLi Eco Tech. I paid for GLI but now i am confused that either i should change to GLi Eco Tech as it has already been discussed performance wise that there are 4 intakes of CNG which makes performance some how equivalent to petrol. Plus i dont know if its a rumor that petrol head is not stable on Local CNG fitted GLI not the eco tech one, dont confuse with it.. I heard that Liana also launched the same technology five years ago but it was a flop. As in this technology a local mechanic cannot tune it so we have to get it tuned from company which costs way to much high. So guys suggest me what should i do , me total confused...!! Please, some expert tell me the advantages and disadvantages of local fitted CNG in GLi and GLI eco tech, company fitted...!!!
