Great shop here at HB Speed very knowledgeable and their waiting lobby was pretty cool. Sick cars inside the garage as well.

As far as the tune it feels more peppy and pulls strong. I was expecting more of a kick in the panks kind of change but its noticeable.

I was also shooting for 300 awhp but i was short but i think on the road i will be doin more than 300 because my hood was closed and i wasnt getting enough air flow. I thought the headers and uppipe would get me more top end HP but my tuner said its my snail dying out. They didnt reccomend a boost solenoid either, although i think it would have helped me make more power.

Do these numbers seem low to anybody?

I was hoping to be holding more boost at redline but Jon said 14psi is good. I was shooting for 16 lol.

Tell me what you guys think.

Looks pretty good for 91, especially if your turbo is on it's last legs...

Boost solenoid probably wouldn't have done much, as you are only running 18 psi

What do you mean my turbo is on its last legs by the way??

If i were pushing more boost would it be bad?

The VF-39 can take more boost, I run 22+ psi on mine on 93 oct. I know people running 27+psi on race gas on the 39/43

The limiting factor is probably the quality of your gas

Tuning is all about balance. More boost does not necessarily mean more power. Most stage 2 STi's are physically incapable of efficiently making more boost up top and the amount of boost in the midrange is largely dictated by fuel quality. 18 psi tapering to 14 psi is right about where most of the Stage 2 STi's I tune end up. You can run a bit more boost in the midrange but you'll end up having to give up timing or have to run richer which will kill the gains from increased boost (given CA91 octane). Waaaay too many people get all hung up on how much boost a car is running without thinking about the other factors involved in tuning.

Yes, OP you are the typical annoying customer that thinks they know more then the tuner.

more boost does not necessarily equal = more power, boost solenoid doesnt equal gains in some situations. This is unfortunately when people who read the internet turn their ideas into real life. I think Jon knows his way around a Subaru or two.

ya im pretty happy with the tune. its really smooth also.

Although i keep getting my check engine light and my cruise light blinks also. I thought with a tune it would be able to get that cleared and it never show up again?

well everyone says my numbers are good, so i guess ill just shut up and take what i got.

I think with a fuel pump and a boost controller i might have been able to break the 300 whp mark, maybe even pulled more TQ out of the beast.

I really thought the headers were goin to give me a power boost, but i got more TQ from them then i did HP.

I'm running a simlar setup and see a bit less whp, but would agree with the rest that it's just fine for the crap 91 gas we deal with. Clark did my tune on 91 oct when new and I'v been running an extra 4 or 5 gls of 100 oct since then. I'm sitting at just under 78k, I run the blend as an added measure of knock protection.
I like the blue on blue, looks good.

Not sure about how your EM works but with my utec the check engine flashes when I get knock. So, you might want to find out. When my top mount gets heat soaked, I get knock. Helps though to have a map selection ability to move to more conservative ones when it happens.

My favorite color! Looks good to me dude. I got Protuned on an access port a year ago, and had to have my fuel Filter replaced due to 88k of junk clogging it up. It freed up some of the restrictions my fuel system was feeling. I replaced the pump while there too.

Mods: Cobb intake
Samco inlet tube
GM Boost solenoid
Invidia downpipe
Hks Carbon Ti
Accessport with Protune (Thanks Hill @ Agile Auto!!)
Fuel was Sunoco 93
HP: 329
TQ: 348
