I had a vararam/ported intake/ported tb/American Racing 1 7/8" LT's w/cats/Borla Touring exhaust and put down 388/375.
You can up the ante by using a underdrive pulley, FAST 90mm intake,dumping the cats,a less restrictive exhaust(ie. bullets) or putting some 1.85 ratio rocker arms.
I have a mild mannered cam and now put down 435/397.

I've made a dynojet best of 397rwhp/387rwtq SAE with a cai, SLP 1.85 rockers, ported intake, 1 3/4" long-tubes, x-pipe w/cats, cat-back and tune. The ported intake wasn't worth much peak (6 rwhp) but was worth as much as 10-12 rwhp/tq in the mid-range. I think with a FAST 90 and u/d pulleys, low 400's at the wheels is possible.

Depends where you dyno 
Here's my sheet from Vararam, ported intake, American Racing headers w/ cats, tune and 3:90 gears.
I'm sure I'd be closer to Doug's 388 above on a Dynojet. I do trap 118 mph in 2000 DA very consistently though, there's a way to convert that but I don't know how. My car weighs a confirmed 3200 with about 1/2 tank.

Why are their numbers so high?

Different kind of dyno, it's a load bearing dyno, not an inertia dyno. It's a great piece of equipment, if you know what you are doing you can use it to tune more than just WOT by specifying torque at specific RPM's so you can hit any spark/fueling cell you want. But most people like only Dynojet numbers so they are more comparable from location to location. You can't really compare it to a Dynojet's numbers it could be 30 higher some people here told me.
Look at the difference pre-tune and after the tune. I felt that in the car, I can tell you that. My car felt like a slug before the tune. Now thanks to HP Tuners and my good friends, I'm getting the tune even tighter and got .2 last time at the track thanks to some logging the runs and some sage advice from a buddy!

Don't be afraid of buying a tune from a well known tuner via mail order, or just buy HP Tuners and learn yourself. Hmmm, actually your altitude might throw a wrench for most mail ordrer tuners who are at sealevel, although they will certainly leave you in MAF mode and won't tweak things too much so you will be safe. You can get some decent improvement with some relatively simple changes you will need to do for headers anyway (turn off codes for example, and turn off torque management). I bought Tuners, it's great software, just a bit of a learning curve but their tuning Forum is a great help and if you find someone local to help you to get you started it really helps. Once you get it you get it but it can take some time to understand it all, I still sure don't know it all.

Yes - that's the before tune and after tune dyno. Surprising difference for all of us including Mike Norris who tuned it.

And the Altitude is exactly why I won't mail order a tune

Yes. Hp Tuner cables license to vehicles - 2 LS2's or 4 LS1's come in every cable. Once you license your vehicle to your cable you can change it as many times as you want. If you want to buy more credits you can for $99 for a LS1 or $198 for a LS2. I went in with a couple of LS1 buddies on my cable and we share it. It's good because we are all learning and we share the knowledge at Saturday coffee/HP Tuners parties now and again. We do most of our tuning at the strip by logging our runs, tweaking timing and fueling a little and logging again to see how we did and see how our times are. It makes the drag strip more fun when you can change timing & fuel without getting your hands dirty! The logging feature is very cool, you can see exactly what is going on with your car. For example, I never knew I was launching as high as I was, and my buddy didn't think he was shifting so high. I also am not shifting as fast as I should be, you can see from the log exacly how many milliseconds it takes from off throttle to back on on the graph. You really get some surprises when you get real data but you can't change things if you don't measure them.
