Will CA Smog istance program pay for a tune-up to help p smog?

I have been unable to p the CA smog for my 1999 VW Jetta. I paid for a new catylic converter and two smog tests ($400 total) and still didn't p. I was not told about the istance program until after the repair and second failure. I've applied for istance but have since read that tune-ups help a car pass smog. (My HC is 110 and max is 100). I'm thinking I just might need a tune-up to help pass and maybe a fuel additive to help. Noone has advised me this way, I read this online. Should I wait for the program assistance (I haven't heard back from them yet.) Will they even pay for a tune-up if that's all is needed?
