Take it to project performance machan. Don't even think about taking it to upul or staff. Anyway, since its not a major thing you can rely on a good garage guy machan. Zaki will do only engine tune ups so I don't think taking it to him will help you. Give him a call and see anyway. To be honest, i've never been to any of the garages mentioned here other than zaki. I go for someone who I can rely on. It's up to u macahn.
