Default Question about my Tune?? Please help

So recently i got my 02 Z28 tuned and im curious if im making the horse power and torque i should after the tune. For those of you guys with experience or similar mods hopefully you all can help. Here are the mods i have :

LS1 only has 33k miles on it.
kooks 1 7/8 long tubes
Texas speed true duals
160 degree thermostat
SLP cold air intake with ram air kit
KN filter
Smooth Bellows

After the tune i am making:
332 rwhp
250 ft pounds torqe
Can you guys with experience please tell me if this sounds correct?? thanks for the help.

Torque seems a little low, but HP is pretty close. If this was a mustang dyno, I'd say you're doing ok.

I say 350 rwhp and 300 trq, would be the norm with ur mods. Who tuned it and what kind of dyno? Also, dynos lie and you need to take it to the track. Got a graph to post? Need to see the curve and afr

250 ft/lbs. of rwtq is low. You should be right around 300rwtq. Your rwhp looks right for the mods.

You guys really think 250/300rwtq sounds right for a bolt on car? That's not near what it should be around, I made 353rwhp/343rwtq with my bolt on only ws6 back to back on two different dyno's 2 hours away from each other. 353rwhp/363rwtq in my bolt on c5. All of my friends make around the same numbers in their bolt on cars too. There's NOTHING wrong with your car? I don't see at all how that number can be right.

Alright, that sounds MUCH better. For your mods I'd say that sounds right about perfect. 250rwtq was absolutely ridiculous, they don't even dyno that low stock lol.

Unleashed Performance in Georgetown ind. I do have a graph that i can upload tomorrow but they did not give me a before and after which i thought was a little odd. Do most places give you a before and after graph?

I've never done a baseline run to see how much I gained, while it would have been nice I just didn't want to spend the money at the time for an extra run or two.

Are you an m6 or an a4? I was an a4 with factory stall and gears and put down 343rwhp, I had a few more bolt ons than you (under drive pulley and such) so I don't think 332rwhp is too low, unless it's an m6, those usually dyno a tad higher because of less drivetrain loss.

A4 sounds about right. Car should be a blast to drive if he tuned the transmission at all.

I really want to get a C5 vet. If only they weren't about 10k more than my my Z with similar miles.

You really don't have a full list of mods....Power isnt bad IMHO....The LTs are about all you got making the biggest gains. The other things you have done are worth little RWHP.
