2 or 3 times today over a chip.....is there a reason you are doing this? It may be a little misleading to those who are looking for more hp and they may think this is a viable solution. THIS IS NOT A VIABLE solution right now....

Stick with a chip that will add the right amount of fuel, timing etc...not just more boost

Default Yeah its to bad the Apexi couldnt just wire itself in..but I think the Motronic makes it to

difficult.. i believe that boost controllers are awesome...but most applications are designed for Toyota, Nissan and Mitsubishi...with the others used for stand alone engine management systems with custom turbos...not knocking anyone...but are people aware how difficult it is to program these things let alone wire them up? One bad parameter while dialing it in and boooooom!!! you better have some spare motor parts.

Hello everybody. This is the first time I posted here. I came from the Diamond Star family but decided to grow up and bought a wonderful Audi TT 225 three months ago. Boost Controls can be safely utilized if you understand your own turbo/engine setup. i.e. Stock boost, max safe limit for your turbo, Max exhaust temp before parts start melting. Another words it is not for the inexperienced. If a person decide to go with a boost control instead, they should make sure that they have a boost gauge, exhaust temp gauge, and an Air/fuel Ratio gauge. Not to mention know how to read them. Access to a Dyno would make things simpler too. The stock computer will allow some room for fuel and timing from the increase of boost but it has its limits. That's when other devices comes into play. i.e. timing control fuel control. I believe in Electronic boost controls over a chip because of the amount of growth that it provides and the fact that you could just turn it off.(Then again, APR has a chip device that you could turn off too)My personal favorite Boost control is the Greddy Profec-B. This device is not a Fuzzy logic type like its more expensive brother. It allows two boost settings and is more simple to set up then the Fuzzy logic kind.

Default But Sean, your wrong....

Your statement "THIS IS NOT A VIABLE solution right now.... " isn't correct. The split second is a solution. Granted it isn't the MAX hp&torque for the engine, but it IS the most bang for the buck. Not everyone is going to fork over 1000 for a ecu+chip.

Even with all that crap you still lack control of transients.

Default Like I said, a boost control is not for the inexperienced. You..

need to have a good understanding of how a turbo functions in relation to your engine. Not to mention, self control. Boost can get addictive. For those who want to get their feet wet, you may want to try the Split second unit. It attempts to simplify the process and limits the amount of boost to a max of 14.5 psi. This is hardly enough if you have a 225 TT. If so, try the Greedy Profec-B. Have the unit installed by a pro. Do not have it done at just any speed shop, get it installed at a place that is involved in racing. They will even set it up for you.

Default No Jason your wrong.... =) Comparing a $1K chip & ecu to the

BCS is not a fair comparison.

Compare a BCS to a chip, an ecu is an option to keep a stealthy install. BCS does not have this option really (unless you want to remove the unit)

You state that the BCS is a viable option. Just because it works does not mean it should be an option. I could put a manual boost controller (aka dial-a-death) on my car to crank up the boost.

I could mess with the wastegate actuator rod so it would open sooner and longer producing more boost.

This does not mean that it should be done.

The factory setup is hard to beat when it comes to control of fuel, timing and boost. The BCS controller does none of this.

Jason, if you would like to use the BCS be my guest but I am just trying to tell you my thoughts.

Default I was considering a boost controller for some time...

But not the BCS, but the Greddy pro-b.

Being stealthy has nothing to do with being a viable option. When I said a viable option I never considered stealth as a viable. If I wanted a completely stealth option, I would not even mod the car. I would wait until my warrenty runs out and start modding then. Now with that aside....

You could mess with the wastegate. Change your K03 internal wastegate to an external. Adjust the spring rate so it stays closed longer and give you some good neck problems b4 your 40. :P

Could also get a fuel controller and add a 5 BAR(!) fuel regulator and dump fuel in along with a engine timing controller and a boost controller to accept the extra fuel.

You would also change the cams to 300degrees to bring the power higher on the power band.

Anyone can do this. This is all an option. But you gotta know how to mod the car yourself.

If you want a "no brainer", "slap that sucker on", "I just mod the ECU and have no idea what it does" mod, yes, $1000 chip would be the best option. As ScepTTor said, it isn't for everyone....

You of all people would know what I'm talking about, considering you put a hugh FMIC on your car.
