After various upgrades, I had my FA5 professionally tuned. I am really underwhelmed with the results. I wanted to get some feedback and see if I am being naive about expected gains or if I got a poor tune. Based on other posts with similar or fewer upgrades, I was expecting something in the ~215 whp range. Instead, I only hit 191.9 whp. Here is a parts list (dyno results attached):
1.) Takeda Cold Air Intake - aFe TA-1004B
2.) Grams 72mm throttle body - G09-05-0001
3.) Skunk2 intake manifold - 307-05-0325
4.) DC Sports header - HHC5524
5.) Invidia Cat-back exhaust - HS06HC4G3S
Thoughts?
Professional tune, very poor returns. Naive?

Re: Professional tune, very poor returns. Naive?
Where is the "before" graph?

I wasn't provided with a before graph, unfortunately. The tech said it was ~175 whp
Re: Professional tune, very poor returns. Naive?
Without anything to compare to it is really hard to say.

Re: Professional tune, very poor returns. Naive?
I understand that, but if everything was stock before, we know within a few whp what that would look like, correct?
Re: Professional tune, very poor returns. Naive?
it's not just about peak power. you have to look at the overall powerband
Re: Professional tune, very poor returns. Naive?
You have to be able to see what the change was, as all dynos read differently. You can really only make a comparison knowing what it was before and after.

Damnit. I knew there was some variation between dynos, but figured it wasn't a big deal. In retrospect, I feel like an idiot for not calling them out on the lack of a pre-upgrade dyno result.

compare it with another car in order to see how performs :)
