Hp/tq numbers

I just got back from the dyno and put down 400hp and 360 or 370 TQ...does the tq number seem low for a 383? If it is, what would be some things to check out?

That split is more indicative of a 355 IMHO. I would expect the two numbers to be closer together on 383. Mail order tunes dont replace a good dyno tune. Might be your tune.
What cam?

if the tq was 370 that might be a little low, but not too crazy. what kind of dyno and also weather can have an effect on the numbers. auto or manual?

The dyno was a "Dyno Dynamics" and the weather was a little humid but nothing major...the car is a M6
