Question about tuning..

Ok so the car barely runs....and everyone is saying i need tuning badly with the setup I'm running ( i guess the previous owner didnt match the engine too well). But everyone says it'll be fine with some proper tuning. Now im alittle confused on how tuning works. Ive called around to local shops and got a few that will say they will look at it but that they dont have too much experience with speed density. What exactly will they do to the car? and Is there anything I can do that would help the car out. I know i will probably need a new prom since the stock one just won't do with the way the engine is configured now. Is there a place i can send my cars specs too and they will burn me a custom chip?..i know its not the most effiecent method but its hard to find a place around here that can do a new prom for me...

Any help is appreciated..thanks guys
