MY07 TB STI + C&V Tune = 166atw

[pips06]

Had my MY07 Tb STI tuned by C&V the other week. With a Phat dump and custom 3inch midsection the car made 141kw atw, the C&V tune took it to 166kw atw.

I dont really know the ins and outs of the dyno graph but the car feels MUCH better to drive. Obviously the stock mufflers are preventing me from getting the most out of my exhaust but i'd like to keep the car reasonably quiet for now. Im not really sure where to now in regards to performance mods without replacing the mufflers, any suggestions?

Sorry about the pic

Nice work mate, I have heard good results from C&V tunes….enjoy.

Btw IMO I noticed that after I fitted my centre pipe things got a lot louder, I was running my car with a phat dump and quads, response was better then oem exhaust set up and sound was minimal.

You could try selling or swapping your centre pipe for some better flow cans, or even consider getting your centre pipe made using smaller diameter pipe, which could allow for a mini muffler to be fitted…...

Nice work mate! Pretty nice result

Is your car auto or manual?

I'd replace those cans with some nicer flowing ones (Although may get rather loud)... Maybe a HKS panel filter & a larger TMIC is next on the list

Car is manual.

Oh, i forgot to mention i've also got a HKS panel filter.

I actually found that going from a phat dump to phat dump + custom mid only made a very slight increase in noise.. barely noticable. In fact my g/f didn't even notice.

I have seen quite the opposite Maybe they got someone in to do that one. Thats what they do for certain setups.

Pull a copy of the rom

A bigger tmic will make some gains with this set up I believe. Congrats on the mods and results. Stock mufflers are restrictive as well and replacing them will help too.

[pips06]

Can someone elaborate on how a bigger TMIC will get me more gains? Presumably a bigger TMIC will allow more boost????

Cheers

Great results, Ben! I was there getting a tune when you booked your car in over the phone, so I knew you were coming in for a tune. Glad to see you're happy with the results, which is all that matters.

Dave's suggestion is excellent. A larger top mount will allow for better and cooler flow. You'll notice a nice increase in the mid to high end. But the best part is, no noise increase.

However no matter what you do to increase the incoming air, if you can't get the air out fast enough it's not very efficient. Those stock mufflers is your weakest point right now. Either more resonators or mini-mufflers is in order, or perhaps invest some money in sound insulation which will do wonders.

I have seen quite the opposite

Not me. Haven't seen anything negative come from there yet. Con's one of the top tuners in Australia and I've pretty much know of all the Libertys that have gone through C&V. And keep in mind we are only talking about Libertys here.

Maybe they got someone in to do that one. Thats what they do for certain setups.

Why would they do that? It took a while but Con's finally tuning LIbertys as all tunes are done by him.

[parso_rex]

nope Libertys are not my target market. Its european vehicles for me so forget that line of thought. I can do them of course and I'm doing an Ecut3kd car next week in fact Its just that I've just seen some very very ordinary tunes come out of there with ECU's far far less advanced than a Subaru. I do know they use third parties to do some of their tuning and there is actually nothing wrong with that at all. If I saw the rom or a couple of maps from it, I would be able to tell in an instant if they'd done it properly. For the Liberty's I have my own very well sorted roms and I have no need to copy I'm always interested to see how others go about their work though. FWIW pulse do a very good job but allow a grain of salt or two for the dyno figures
By the way C&V did my 99 Wrx and tuned it Unichip and I actually like the guys. If Cons doing then I'm very impressed and I take it all back

what are ROMS?

Thanks Jim. Im quite happy with the results although the car seems to be idling a little rough since the tune so im taking it back to them tomorrow to take a look.

what are ROMS?

ROM = Read Only Memory. Computer speak mate. In the context of this thread it refers to the parameters that are stored in the ECU memory which refer to how the computer controls things like spark timing, fuel injection timing and amount and throttle behaviour. It is information that the ECU cannot modify when running.

ROM is similar to RAM (random access memory) on your computer. The big difference is that the computer is able to read and write to (modify) RAM. It is not able to write to ROM.

Mark
On your dyno at the dyno day mine read 144 with Phat dump centre and mufflers and no tune
Amonth later took to C&V ...Con did the tune , I was there all the time
before the tune on his dyno it read 136 and after read 168 so a similar result to Ben
Now it is only figures comparing dyno's..... + or - a few kw can be many things but I can tell you that the 30 odd kw gained has transformed mine ,slightly quicker off the mark and really hauls from 3 all the way to redline without seeming to run out of breath as before
The only thing as Ben said is a slightly rougher idle that is about 100 revs higher than pretune, that I did notice at the start but after a few days I had forgot about
I know you aren't trying to score points or knock anybody's rep , wwhen it comes to dyno's from some places it is easy to be sceptical , only good to be used as a comparison before and after tune on the same dyno with no changing of parameters, and a figure does not tell the whole story- how the car drives is the true picture of a successful tune, and I am pretty happy with my result

[parso_rex]

Maybe I'm a bit too harsh in this case, sorry about that. At the end of the day the butt dyno will tell you all you need anyway. I just see a lot of guys getting taken for a ride at various shops round Sydney (no not C&V) so I'm always sceptical. There was a guy doing tunes in wollongong on WRX's for $1k no dyno runs, everybody thought it was a bargain but all he did was modify the last column of cells in the boost maps and mess with the fueling to suit. He's not the only one either. This way you still get a nice high dyno figure on a power run but its just not as good as it could be anywhere else. For cars with after market ECU/s its worse again, hardly any place seems to bother about anything but the top end so you end up with cars that don't idle and use way to much fuel with lower power and torque across the board.
I don't touch anything in the idle areas of the maps on a car with stock injectors no need
PS nice Edit Arith

All good Mark. I can understand your skepticism, especially when it concerns the tuning world. I too have heard many horror stories from Phat and other sources in regards to some of the tuners in Sydney. But there are hardly any tuners who can do the Gen IV Liberty, let alone the MY07+ Liberty. With the exception of the Haltech Interceptor, there's actually no aftermarket ECU unit that was fully compatible with the MY07+ ECU's that didn't require you to give up something. Sure, there's MRT who locks in your ECU and you have to take out a 2nd mortgage on the house to pay for it, but only x2 reputable Sydney tuners that I know of who can do OpenECU tuning for the Libertys. But I directly know the people or have heard stories about all the Libertys that have been to both, and I can tell you both tuners are legit, do the tune themselves, and offer the full service of tuning and dyno runs. Opps, sorry to hijack your thread Ben.
