The Boost you have is pretty good compared to stock Comptech which is around 5.5psi.
And if your gauge reads 8.2psi than thats pretty high.Anyway where is your boost sensor installed?
All i can think of to have your enigma solved is to dyno the car witout the SC and see what the SC gives you.
If you produce 180whp without it than you have great gains over Stock...
And if you produce something like 210whp than you have to Puzzle what is wrong.And try to fix it if that at all possible.Anyway i have a suggestion on a test you can do.If you can find a friend which has a Comptech Stock or a Vortech,go on the highway and do a couple of runs and see how your car-power compares to him.If you are even,than,there is definetly somethnig wrong.
Cheers.

I think that is a little low for your mods, but then conditions may have been bad. Heat, humidity, and/or altitude can all have an effect.

I have the CT SC w/AC, Rick's header, Invidia test pipe, and CT exhaust and I put down 300.5 at 2600 feet on a DynoJet.

I'm not sure what the elevation is in Milwaukee,WI.
Humidity wasn't that high and the temperature was around 70 degrees.
I'll have to go look at the dyno chart again.

I am still dissapointed at the results though.

Two BIG things.

1. All dynos read differently. It varies by brand, location, model #, dyno operator, car, humidity, cheating, and sometimes whether a butterfly flapped its wings on the other side of the world, etc. . . . Without a before and after, any dyno comparisons are meaningless. On top of that, I'll bet that you can't tell the difference between 280 whp, 300 whp, and 320 whp (most people have wildly inaccurate and inconsistent butt dynos).
200 dynojet A whp =/ 200 Dynojet B whp =/ 200 Mustang dyno whp =/ 200 DynaPack whp =/ 200 Superflow whp =/ 200 Dyno Dynamics whp

Dyno it somewhere else. You may just get the numbers you're looking for. Raw numbers suck and are incredibly misleading. I hate to say it, but people with your attitude are why tuners who have high reading dynos are sometimes considered better tuners than those with low reading, but accutate, dynos.

2. Based on their response, I have no reason to doubt King's tuning skills. It sounds like King did everything right except for giving the owners son more info about what they did and how they did it. While not ideal, that doesn't make them bad tuners.

If I had a car that drove well and my tuner put 100 miles and 31 dyno pulls on it, I would be happy. If the drivability sucked, I would be extremely pissed. Luckily, I tune my own car... If your dad is happy, then they did a good job. 100 miles and 31 dyno runs sounds like a lot (and is), but that alone is NOT enough reason to be pissed.

King's excuse about the IAT, CLT, *knock*, and WBO2 tables is weak. Those tables take at most 5 minutes to fix. Anybody who has tuned a S2000 before should have a map with them already correct. I can import the correct tables from an existing map to a new base map in under 2 minutes (most of that time is starting up the program). I do understand their point about VTEC, but I think they overstressed it. 10 runs just for VTEC is NOT excessive, but it also shouldn't take more than an hour.

To tell the truth I can't tell the difference in power when we didn't have the supercharger and now that we do. My butt dyno sucks.

But hey I give them credit for doing a clean job and waxing the engine bay spot less.

How can you not feel the difference? You'd have to be in a coma unless you'd never been in a stock S2000 before.

Here's my dyno with just the Vortech SC and Invidia catback exhaust at that time. I don't know what happened on your dyno..... but it seems low for all the modifications you put on. How's your air/fuel ratio? and also I don't know about the Godzilla BOV..... i think you lose hp from that. Also try to do a dyno on a Dynapack dynamometer you'll probably get more hp.

Yeah...I cant imagine how you couldnt feel the difference...At first few days as i had the SC on i didnt think i could get used to it and handle the car...now its comon once you get used to it and you think more boost...
And yeah take off the belt and dyno it without the SC.
