HotrodS6

Hello, I just bought a S6 and am about to start do some upgrades. First thing is the boost gauge and possibly a boost controller. I am curious what is the max safe boost I can run with this chip? I am also going to adjust the waste gate. The car feel kind of slow and I know the S6 can make some power. thanks Sam

MTM 1+ is programmed for about 22 psi with the 3.0 bar pressure transducer. This will make 270 HP/310 ft-lbs of torque.

The MTM 1 with 2.5 bar PT make the same HP, but less torque (280 ft/lbs).

A boost gauge is good idea, but a boost controller is not.

But have the chipset installed. You don't need to crank down on the wastegate or use of any controllers.

If you want a boost guage, the only way to go is the TDS-1, IMHO.

The recent updates allow scalability down the road as your car gets faster. For now you can plug in and see Peak/Hold boost, IAT, and there are other modules you can add later to display wideband O2 (Air/Fuel), and fuel pressure monitoring.

This all works out of one neat control box that's hidden and will display these values on the stock AutoCheck screen.<ul><li><a href="http://www.034motorsport.com/product_info.php?manufacturers_id=&amp;products_id =596">TDS-1 Boost Display (034Motorsport)</a></li></ul>

So this engine can't be controlled by a manual boost controller? How is boost controlled, by a boost control solenoid?

all the sensors out of the equation when calculating boost such as intake air temp, ambient pressure.

Boost is controlled electronically by the ECU which sends a signal to the waste gate frequency vavle, which uses vacuum/boost to open/close the wastegate.
