well they usually takes 300rp for my 660cc japanese car (computerised .. c.n.g tuning./) ..liken their work is superb.. and for their charges thn it depends upon several factors.. like the displacement of car,,efi kit.. etc etc.. so u may call him at first and ask the exact rate..
and if u want his no. thn tell me ,, tommarow i will give u. inshallah
