how does the merge on your Y pipe look? my jethot y pipe merge was horrible. it was more like a "T" than a "Y". i added a real merge collector. you might wanna think about that as well as everything else that was mentioned.
did you ATAP your dyno runs? you should have. always atap when you dyno. if you did, you wanna show us the logs? you'll get it worked out....

I have a reciept on my desk for 6300 dollars for my H/C ,thats without labor,You did good...Now I lost 20 horsepower when I Dynoed in early July over a dyno from a couple years ago. I associate it to plugs getting old and a humid hot summer day. I bet if you go back in about 90 days you will get better results. 390 horse power is a Big number. You shouldnt feel bad. It honestly looks close to me. I was thinking 400 range....Is that through a 10 bolt?

You pay for what you get.
Also, I'd highly suggest getting EFI Live to monitor your setup.

Check with TTP for Kooks and QTP for the QTP headers.

You dont need high dollar headers that look/fit pretty to put down good numbers...I personally think those Edelbrock stepped 1 3/4- 1 7/8 look to be promising. Granted, the Pacesetter Y is ****. I think you are just losing a few hp here and there and it caught up with you. No ported TB, no ASP pulley, dented headers, crappy Y pipe. The cam is a reverse split, but its so small of a reverse...it is definitely more than capable of putting down 415+ rwhp with the right setup. How much total timing advance are you running? Who tuned the car?

APE tuned the car, I think I am at 28* timing, the cam has 4* built in, but I am not sure 100%
Yeah, the headers are restricting be a little, I also think 40* worse weather played a big part in it.

Even a slight crush in a primary will kill its flow. If you have several dented pretty bad it would definitely be worth 30RWHP EASILY
swap out those headers and redyno.

One other thing. Reverse splits (Especially large reverse splits) like as free flow exhaust as possible. Open headers work best. With the crushed primaries and Ypipe on the car you arent going to be taking advantage of that cam. A standard split would work far better.

I agree with most the others when they say you need to finish up your exhaust before expecting big numbers.
Dyno numbers don't tell everything, the track does.
Now if you want to be a dyno queen, get yourself a ported TB (or FAST 90mm intake/tb if you got another $1500) and do the shortbelt mod for the dyno. Even if you were making peak hp with your combo, I don't beleive stepped headers would be worth the $$$ invested. Get a set of Kooks or QTPs and a good Y or go duals.
Not knocking you or anything, but you should have researched your combo a little more just so you knew exactly what was going to happen.
I think you should get back on another dynojet just incase. You don't want to go dropping more money if you don't need to. There's always a chance for a glitch.
And for the record, I do think you should be making more power. I put down 380 to the wheels with bolt ons and a ls6 cam only.

Get a ported tb and pulley-Your prob losing about 20rwhp/20tq. Get the headers checked out, if they are damaged-replace/repair them. Find a nicer set of used headers, the quality of the pacesetters is lacking. What are your goals with the car? Do you drag race? This horse has been beaten into the ground, but here it is-the dyno is a tuning tool. Get your issues worked out, take it to a prof. tuner and get the car dialed in on the dyno. Then take it out and have some fun with it.
