Default 07 STI Limited Buschur stg 2 w/dynoflash tune

Well I installed the Buschur Stg 2
BR Uppipe
BR 3inch Turbo Back w/Catted downpipe and quiet muffler
BR Intake
Cobb AP (went with this instead of the reflash, has to many fun options)

Then headed off to Buschur Racing and Al (DynoFlash) for a tune. Here are the results (as seen in the Buschur Thread)



I am very happy to say the least. The car responds well, runs smooth and is a blast to drive!

David and the team at Buschur are great guys and I am really happy that I went with their parts!

Al (DYNOFLASH) did a great job with the car. Untuned the car put down 260whp and 230wft (w/Stg 2 installed, sorry no baseline stock numbers). He really does know what he is doing.

We basically ran out of injector and had to leave the tune where it is. Had I known that this would have happened I would have installed a fuel pump (Buschur tried to find time in their busy schedule to install one but it just was not meant to be) Goes to show you how much they are willing to help!

Now I just have to see how long I will be happy with the car at this level.

Keep up the good work Buschur and Dynoflash...

Chris

So Al protuned your AP, then? I asked him how he tuned it on EvoM, but didn't get a reply.

I'm surprised they put a cat in their DP, that isn't very BR-like; but from what i've gathered, this is normal in the subie world? Can you post some pics of the BR exhaust?

I don't think you are taking about the same car. The one on EvoM is a WRX and not an STI, but yes Al protuned the AP for me while I was out at Buschur.

The reason for the cat in the DP is based on where I live. I live in Philly and wanted to be sure that I could have a fighting chance if I needed to worry about the inspection. I think had a done this over I would be cat free.

I will take some pictures over the weekend and post them up.

Final numbers are 299whp and 339wtq (although I know that saw a run with 301whp and 34Xwtq), so the tq is higher.

It was only with no tune that the hp was higher.

Yea, I drove 7 hours to Buschur untuned! I took it pretty easy on the car the whole way. Never really pushed it.

Yea, It does suck to have the Catted DP but better safe than sorry. I may change it out though! (depends on how long I can keep myself from going green!)

Thanks for the great review

having a catted down pipe has its advantages

boost creep is minimized and its nice to be legal on a street car - also its quieter in fact its so quiet with the BR quiet muffler I think even the largest pig cop would be pleased with the mellow tone (those in CA will know what I am talking about - they treat car modifiers as ' street racers ' )

Needless to say the power was very impressive to say the least even with the cat !

Buschur uses a very high cost and high performance cat unit which is not as bad as you might assume

Controlling the boost on the stock boost hoses can be hard on a 07 sti if you run a catless down pipe

Those who run a AP base map should be advised of the TSB cobb issued on the boost control issue on 07 vehicles due to a smaller boost pil

Al

PER COBB - -

Added 04/16/2007 - A Service Bulletin has been added to educate AccessPORT users about the potential overboost issues that may occur when operating the vehicle with a catless exhaust system. A link to this Service Bulletin should be up on our website by the end of this week. This cannot be tuned out and the boost control system will need to be mechanically revised in order to remedy this situation from those who's 2007 WRX or STi suffers from this. Another options is for you to install at least one high flow catalytic converter to help prevent the turbo from an overrun condition (boost spikes, boost creep, and higher than desired boost #s). Again, more specific details of this are covered in this Service Bulletin.

Nice boost spike - leading to your torque spike - resulting in your slightly inflated torque number - and also resulting in a horsepower curve that is not as smooth as it should be.

Come and take a look at the car with the Cobb AP attached. You can see that there is no dramatic boost spike! Car runs smooth and pulls hard, but to each there own. Take a look at the tq numbers on most of the 07 here... they all seem to shoot up and then drop.

But if it does spike it is not something that is noticed or a large spike. I have faith that I did not leave Buschur's with a tune that is going to endanger my car. Al really did a good job and David produced some great parts!

Yeah could be smoother. Not a bad tune for a lawyer.

Nice job actually Al. 07 STIs are nice.
