From what I read sti panel filter, plugs and remap should give a decent increase. But if I'm right and my current ppp map is very restrictive, I might get even more with a remap. I any case, for sure I'll make an rr before and after remap.

What was the other car ? i know my STI PPP is a lot quicker off the mark than a mates FST and another CTR, I would say there is a lot less in it once off the mark.....which is why I'm paying a visit to Mr Rawle on Saturday, I only have 6 months warranty left as well

the redline is at 7.3 k so no never did redlining, and at 5k is pulling well. If I chnage at 5k not at 6.5k, it drops to around 3.5k and when I boot it, it kinnda stuggles(it doesn't pull as hard) till it gets to 4k -4.3k then pulls heavily till 6.5k even 7k, I don't feel any loss. Never went above 7k, but like I said redline is from 7.3k.

Thinking about this, you might be close to the truth. As I do remember that on high speed, 100 + it was going better than my bug wrx ppp, but I thought it is more down to the gearing(6 speed v 5 speed) and of course some power.

If you were running 300hp you should have the better of a 200hp 1400kg fwd IMHO.

And it just reinforces my view that smth is not ok with my car. I can onlythink that the map is not done well, but who knows. This assumption I have as it seems that my sti doesn't care if I use 97/98 octan fuel or 100 vpower,it pretty much goes the same. Honestly there is either no difference or very little. I know this as my old wrx ppp had a huge increase when I used optimax, I mean you really really felt it was going, but the sti doesn't seemto care. If I use 95 it goes a bit worse, I feel that but not much worse tbh. Hence I'm thinking there is smth wrong with the map. Not sure how it can be checked, but I'g going to call my dealer and try to make them check it

might sound like a silly question but have you had it from new and do you have ppp cert, if you were close enough we could have compared.maybe there is someone near you

The closest tuner to me is in germany, and looking at their site I see they have a pic of a map on an sti. Seems to have rr's too.
Here is the link: http://www.koch-subaru.de/files/suba...at_by_koch.jpg
To mee it looks like the drop in torque is too soon, but I'm wondering what the rest of you think about it. I don't know anything about them.

i wish i could find my graph for you mate, i took it on a rr just for piece of mind that it was ppp'd, it got 309bhp/284lbs torque. think prodrive say 305/299. thats not to say the rr wasn't giving an accurate reading. i know you don't want to start a 'versus' thread but you'd get a lot more answers about wether it has lost power if people new what you compared it to

Have you tried resetting the ECU..?
Easy peasy, just disconnect the battery for 30mins. See if it makes any difference. Ideally run a few tanks of vpower though it and then reset it..

There is no rr where I live so no. But is down on power for sure. I always felt that is not faster than my old bug wrx ppp, now now for sure, so smth is wrong. I'm thinking that before modding I will go to dealer, but I'm afraid they will be reluctant to even look at it or will just say is ok.... So then I'll just remap it. These are my thoughts right now anyway
Are you sure its a PPP Sti not a normal sti ? it should blow away a 200bhp if its a proper ppp sti

Not at normal driving speeds, mine is now at 340 bhp., but before near standard I got loads of grief from "bouys" in hot-hatches. I've grown up now...

P.S. My pal Jamesemt has a re-mapped Ibiza diesel and it's got less weight and more torque, you guess which is quicker !

I'm runnng 98 fuel, but the 300 bhp claimed by ppp is with 98. Also like I said before, running it on v power made no difference, and that I also find very strange. I didn't try ecu reset, will try today or tomorrow.

I have an appointment with the dealer to check it out, but I have to wait 4 weeks 
They said that I might be right and it doesn't make the proper boost it should, so they are going to connect it to the diagnostic computer, and check it out.
Meanwhile I can play aroud with the sti panel filter and an ecu reset

You could have a faulty Neutral Position Switch, which is common on these. I've had mine changed.
It controls the VVT and you will be well down on torque.
If you're going for a remap anyway, it will be easily indentifiable if it's that.

Well, I have the certificate, and I see the prodrive backbox. Other than that dunno, and yes, this is why is annoying me, it should have blown away....

As regards using V-power, without a reset it will take at least two tankfuls to notice a difference..!
I wouldn't change anything (STI panel filter) before going to dealer, as they could say that's the problem IYSWIM..?
Run a tank or two of v-power then reset..

well, the good news is that I found a place where I can have it rr'ed, so I'm booked there for next Saturday. Will post back the result. I must say I can't wait to see the result.
