How much power is missing?

Took my 99 SS to the shop to get a couple of dyno runs and I was shocked when I saw I was only putting down 319 to the wheels and only 302lbs of torque.I was hoping for at least 350+ horses-My mods are:

1.Custom TR 230 Cam, Specs are: 230 230 .575 .575 114+3

2.Pacesetter Long tubes and y-pipe with cutout open

3.Slp lid

4. Street tune by a local shop

Also the Air/Fuel readout was a little shocking it was at 14.4-14.5 I don't exactly know where it should be at? what do you guys think?

Car is a A4 with stock converter

Car is way too lean and prolly getting knock retard and pulling all the timing out. Car should do 345-355 with those mods through a stock converter.

If you took it back to the same place for a retune please take it else where as they aren't doing a good job of it. My a/f ratio is 13.4-13.1ish across the graph.

Do you have a graph of the dyno runs?

I wouldn't feel bad, if you read the other thread I posted in, I got royally fisted with 265whp on a Dynapack 3000 from my cam only 99. The TQ converter was supposed to be locked, I couldn't tell if it locked since he wouldn't let me drive it when it was on the dyno. Oh well, numbers are just numbers. But for what its worth, 12.1 is rich as hell for a car that doesn't have any forced induction.
