Whats wrong? look at my dyno-
I just had a 224/228 .581/.588 112LSA
LS6 intake
Long tubes/ off road y-pipe/ hooker catback
New spark plugs and wires
4.10 gears
and a supposed tune put in my car and this is how it dynoed
370HP and 362TQ (76degrees, 5%humidity)
---Isn't this low? My TR224 put down 375/369 with a slipping clutch. Is there something wrong with the tune? I'm not too happy with the tune right now (Still idles crazy like it did before tune)?
Please help

It is low. I have the same cam with a 114 LSA in an automatic and it put down 393rwhp. I would say you have tuning issues. I know this does not help out alot but I am not good with the tuning. I mail ordered mine through Texas Speed and it was awesome.
I would say your numbers are not too far off. I made 366/360 with a combo the same pretty much the same as yours. I am begining to realize that some cars just make more than others with equivelant mods the more I search around.
That is not very common unless you have heads or something.

Timing does have a major effect but there comes a point in adding timing and getting diminishing returns from it. Don't want overkill that is for sure.
I would say do a leakdown on it, if all is well I would say try a different dyno to ensure that that one isn't off, if that dyno is correct, take it to the track and see what it will mph. Velocity in the quarter should indicate the efficiency of the car. If it traps a high MPH but dynos low then I wouldn't worry, it is just a low dynoing car.

This is probably a dumb question, but would a bac AC Compressor rob me of any horse power? I had to replace mine because it was freezing up and (i guess) putting stress on the belts? (This is what I was told)
