Tuned and dynoed
Tuned and dynoed Took my V last week to Broad View Automotive to get her tuned after a long tube install. I wasnt expecting crazy numbers, but wanted to get a baseline and see the difference in numbers. Also first time getting a car dynoed so it was cool to watch. Tuner wasnt too happy with the numbers, but car feels a lot better and sounds pretty good 
My mods are: K&N CAI, B&B 1 7/8th headers, no cats, B&B x-pipe, B&B exhaust.
Numbers Pre-tune 316hp 323tq
Post tune 335hp 333tq

Yes dynojet, I figured the numbers were stupid low based on what others here have seen with the exact same mods. But in the end they are just numbers; will be getting it cammed and tuned again over the winter so not really concerned.
Damn 370...did think that there would be a 40hp difference. The day I got my tuned was mid 70s with about 90% humidity..damnit now I am contemplating a retune lol.

I have similar rwhp/tq as the OP on a Mustang dyno - they're just numbers. With a header-back exhaust and CAI, my local speedshop typically sees about 365ish with an LS6. That's when they really groom it for dyno-queen numbers.
My tuner asked me if what I was looking for and I wanted something safe and esp to run a little cooler - I'm on the richer side of the AFR. Sacrificed a little HP but I don't care.

I made 343rwhp on a dynojet with just a cai and tune. 365rwhp with kooks and high flow cats. It wouldnt hurt to do a compression test and make sure you're good to go on that end. I'd definetly be suspect with those numbers.
I think i would be looking for another tuner. Those gains are not good. Those are the numbers you should be looking at. Not the peak numbers. You didn't seem to pick up the amount of hp you could have. Mustang dyno or not. I did 382 with only lt and high flow cats. That was on a 105 outside feel like temp with about 90% humidity.
Basically, all these comments are useless because no GOOD questions are being asked.
a) What is the Correction factor applied? Who is to say what D.A. this car was run at.. 335hp at 6000 D.A. and the value is Uncorrected would mean something completely different now wouldn't it? So, what Correction Factor was used or was there one applied?
b)which dynojet model? NOT all dyno jet models are the same (the classic inertia). I used to run an eddy current.. steady state tuning is preferred.
c) These are calibrated instruments that require maintenance, both the drum and the weather stations. Does this shop do any of this?
Time and time again i read it.. varying numbers, blah blah, its just numbers.
usually, its the operator doesn't have a clue how WinPep works, doesn't understand what correction factors are to be used or what the math is behind them, do they even know what MSL is? How is that dusty weatherstation doing?
Most variance is due to everything except the dyno itself (including a lack of understanding which dyno brand does what), which is accurate when used properly both on the value of the number and in comparison with others.

I understand what you're saying and fully understand there are eddy current dynojets. My point was simply to focus on the street manners and perhaps get a second dyno's opinion before getting too worried about things. My reference to the '385' hp figure was from a guy I raced once. I won that one...
