How is my car performing on this dyno chart?

Update - As an (ocassionally used) fast road car I have changed the double din to a single pioneer head unit. Have also changed the standard speakers to a set of JBL components up front and coaxials in the rear. Sound quality is alot crisp and clearer now.
I've also had a Whiteline rear adjustable ARB (set on soft 22mm) fitted. Certainly stiffened up the chassis but am yet to fully test it by throwing the car round corners.
Looks like a new set of tyres are soon due, followed by insurance. eek
Everything else will have to wait, including my next turbo.

Chet, it might also be worth swapping out your TMIC for another STI item just to check yours isn't restricting flow. They seem to vary enormously.
I've seen some WRX's recently making more power than STI's on the OEM WRX top mount - think a lot depends on how much cr*p there is in em!

a lot less than than the 4 bhp origianlly achieved during my last dyno. Just a cosmetic change Harvey, was fed up of having to crank up the pathetic stereo to get a decent sound from it, and even then it was poor quality so changed it.

For example, it's unlikely a partially blocked STI intercooler will make as much power as a well maintained WRX item

I would think a blocked intercooler or exhaust would not show such a good mass air flow (caveat - my experience of this measure is purely Audi RS related). I agree it might be a small air leak (you are pushing the vf35 to the limit, so small leak could result in large drop in efficiency).
I would take Harvey up on his offer, his suggested investigation should leave no easily rectifiable problem unsolved. I would trust him to do similar for me if it were necessary.

Cheers guys, I'm sure Harvey would be able to take a look but just as I've previously posted I am in London and Harveys an odd 400 miles away.
On a seperate note I've already spoken to FB Tuning who will do a compression and diagnosis for me in a week or two.
Keep you posted.
Tubbs, what turbo are you running with your front mount?

Compression test won't take him long, fingers crossed it won't be that.

Update: - had my appointment with Rich @ FBTuning yesterday and who carried out the following work:
• Compression Test
• Replaced spark plugs
• Refitted/mounted boost solenoid
• Adjusted Rear ARB
• Map Tweak
First of all I requested for a compression test be carried out to find out whether either of the cylinders were in fact low in compression, which may or may not be a resulting factor in loss of power.
The results turned out to be fine – so no reason for concern there.
With the plugs removed Rich also checked the condition of cylinder bores by using what I thought was an intelligent piece of camera equipment which allowed him to physically view inside the each bore.
Upon carrying out the compression test I had a new set of Spark Plugs to go on. The plugs which were removed were standard 6’s and in not the greatest of conditions.
The #2 spark plug electrode tip was completed damaged.
Rich did mention with the condition of the removed/damaged plugs these would have contributed to my expected initial power figures.
Rich knew exactly what my intentions were for the car and what he needed to do to tailor my requirements.
With a new set of plugs and all the checks carried out above I suggested the next thing for him to do was tweak the map.
So off we went along some country roads, me sat in the back whilst Rich worked his magic upfront, driving and logging data.
Personally I’d like to know what is being done in terms of the map, the engine etc so Rich was happy enough to explain (of course in laymans terms) how the car was running and what he was doing to tweak it.
Of course with the tweaking being done on road I am unable to provide any figures at this stage but what I will say is the car feels a lot better to drive for a number of reasons.
What I have noticed is I can hold boost for longer periods than before and the power delivery throughout the rev range is smoother too. The overall performance has improved and the car feels better, so has the grunt.
Throughout the entire tweaking process I constantly asked questions about the car and how it felt in comparison - the answers I got back were as if I was talking to an absolute Subaru genius. I was in no doubt that Rich knew his Subaru’s in and out. A gain with Rich is that he knows Subaru’s end to end, whether it is modding/fitting or just mapping; he knows what works well together.
Rich, thank you for your time and knowledge (as well as making one of the best cup of tea I’ve had in a long time). Your workmanship is second to non and the way you treated my car was like as if it were your own.
The bottom line for me now is to get the car dyno’ed or just be content with how it drives on the road, and not get fixated with chasing numbers (which I don’t believe I am).
With my current setup I would have maximised the engine and my only next step forward should I choose is a new billet turbo (18g).
For now it’s about maintaining the car and enjoying it for what it is.

the ones removed were standard (whatever they are) and the replacements ones gone in are the NGK Iridium Spark Plugs 7's.
Which aren't the recommended NGKPRF7b but will do for a year and will change to the NGKPRF7b next year.
Like a **** I had ordered the wrong ones but with Rich's experience with the NGK Iridium Spark Plugs is that they will do for about a year.

Hi Chet
those Iridium 7's should be OK for you,we are run PFR7b at 490bhp and has been spotless
You will see how you get on with those,but PFR7b we are used only on our wagon
You are going with Billet 18G?
Try to hold of MDX321T or MDX555 billet

Cheers All,
Just noticed today I've attracted 2,649 views of this thread. Never have I had a thread which attracted so many views with so little posts.
I hope its informative to you all.

Go on Chet get yourself down SRR .
I'm surprised you don't notice more issues in general driving with a knackered spark plug though.
When my old WRX had a bad plug, it bunny hopped and bogged down massively half way through the rev range.
I'm glad you seem to have a more drivable car now.
I paid my first visit to Rich on Thursday last week to fit my clutch and flywheel.
I was very impressed with his level of knowledge, his attention to detail and in general how willing he was to offer advice. Nice bloke, and I would definitely recommend him.
P.S SC38 will get you a nice mix and you'll defo be happy with it! I'm now saving for an SC42 lol.

Just ordered a set of Vredestein Ultrac Sessanta 225/45 R17 94 Y XL Tyres.
Next road tax and insurance, never ends does it, although no complaints when I'm sat driving it.

Sessantas are great mate, you won't be disappointed.
At the moment I'm pondering what I'll go for end of 2013 / early 2014 when I've eventually killed the Hankooks!
I've had 2 sets of Sessantas and really like them, but I also massively rated the Continental Sport Contacts I had on the car when I bought it, they seemed to produce a phenomenal amount of grip, even more than the Vreddies, but not much experience in the wet with them...
Did you ever get to the bottom of why your car wasn't making power?
P.S. SC42 arrived this morning....there'll be a 20g and Harvey up pipe and headers for sale soon.....not that you'd be tempted or anything
