Well at certain rpms, there is a 20whp difference. But total hp was only a 12hp gain. I just love how it feels now, I just need some guidance on the exhaust!
And I'm not sure what kind of dyno he runs or if it reads low. I'm not really sure.

Viperboy, as for making your exhaust quieter you should get rid of your test pipe if you have one and replace it with a Cattman Fastcat. I had to play around with many exhaust components until I found the right level of sound for me. I finally settled on the Megan CB.

Yes Canadian, and this was over 2 months ago now so whatever the rate was back then.

Headers are mid-top. Hell...those alone should add 12HP, a tune should all more to that. You won't see anything top end with the spacers but mid range should be nice with those plus headers and tune. Just really surprised at how low the top end numbers are.

Cattman headers, Fastcat, and Vibrant muffer. I had no resonator at all in my b-pipe. Pretty raspy once I get up in the RPM band.

Well, not as much as I hoped, but I'm happy with how it drives but I just wish the numbers were a little higher lol 242hp, he tuned it pretty conservatively. I totally forget the torque numbers now but I have the graph. They used a wideband when they tuned it too.
But... The car sounds like a honda at certain rpms.
I think its from the test pipe but it is wayyy too raspy. Would a cat or high flow cat make that go away or should I just get a larger magnaflow resonator, or maybe both???
I wanna fix this asap, and the car needs to get quieted down too lol

as far as the raspiness, return to the stock cat, and it should get rid of that

He's charging you $1275 and he doesn't know to run the dyno to redline? Isn't the point of a dyno to see how the power curve is throughout the RPM range? Is he not going to adjust your AF past 6200 as well since it "doesn't make power there"? Just because it isn't making power past there doesn't mean you shouldn't take it up there, how else will you know how it is behaving past the peak power point. He should know its more about area under the curve than peak numbers.
Yeah... That defeats the whole purpose of removing the speed limiter.

Sorry to hear that you didn't get what you expected.
I don't think the numbers seem low. From what you said you got done and previous mods you stated you had, the numbers you got sound about right.
With the mods I have I am probably putting down somewhere between 250-260 whp after recently installing a megan B pipe. Before the B-pipe I dynoed at 249 whp.
What kind of muffler do you have? Maybe changing mufflers or changing the testpipe might get rid of the raspyness.

so wait, you only gained 12 horsepower from headers, y-pipe, spacers and a tune? yeah something is wrong... your previous numbers might have been off.. but the tune alone should have given you about that
as far as the raspiness, return to the stock cat, and it should get rid of that

I think I will post in the classifieds if I don't find anything around here for the cat. I'm sure someone will give me a couple of buck + their cat.

I have a built in test pipe :-( sorry. Did you get to see his R34 skyline when you where down there? Jason is a good guy and really knows his stuff. I can guarantee you that you have the best tune on that car possible with out having some kind of fuel controler. So where do you live at? Im down here in Vantucky.

Those prices were fair, assuming they were done quality then there shouldn't be any complaints, he got a afc, headers, and spacers installed + dyno time, I added that up and my price on that would be $1,000 easy. For those hating on the price and saying diy, buy or rent a lift and dyno, do it day in and day out for other people, and then comment.
The numbers aren't bad. People forget dyno's are far from consistent, especially between machines and conditions, and even then without the graphs and runfiles we really don't know what's up. I bet his mid-range is sexy as hell. I gained 20 ft/lb's w/tuning on MaximusMorph. car@ aroun 4k rpm's
Just as an fyi, the longer the runners on both intakes and exhausts the longer the pulses = you're going to see better results low/midrange. Shorty headers and spacers without the thick upper-to-lower will own if peak #'s is what you're after. But this is a good example of how sometimes the dyno doesn't tell it all, if he takes out that upper-to-lower spacer I can guarantee he'll lose 5+ down low and gain 5+ up high, but there will also be a loss overall under the right conditions from the manifold getting hotter.
And yes, test-pipes/cat delete give a ugly raspy sound

It takes me no more than 30 minutes to install the vafc. Install and tune is hardly $500 worth of work in my eyes.
And if he said he didnt take it to redline because it makes no power up there, he needs to go back to school. Area under the curve, shift points, etc. You cant find out this stuff, if you dont go to the rev cut.
But as long as your happy with it.

even if he didnt take it to the redline.....he had already made his peak power b4 then....but it was still messed up how they didnt take it to redline

Yes, it is tuned properly. And I no longer have the rear section, I'm just hoping a magnaflow high flow cat or the stock one (whichever I can get my hands on first) will keep the rasp down.

So since not everyone is agreement that you got such a great deal, we should just GTFO (as you say)? Maybe you should have kept the figures to yourself and less people would think that you got ripped off.
WTF does that even mean. I don't waste my money on go fast parts for a beater daily driver like some.

My point is you posted twice, in fairly harsh terms, that the thread OP paid too much for his install. You made your point on the first post. Was the second absolutely necessary?
You're a moderator. I would think you could show a bit more restraint.
There's also no need to put down those modifying their daily drivers. I bet the vast majority of .ORG members are also modifying daily drivers.
