If the ECU is controlling the boost you should be able to bypass the n75 valve and control things with a manual boost controller right?

Anyway since this thread is about weight reduction, have any ideas for dropping some weight? I have an a6 and its only around 200 lbs heavier than an S4 (would you believe the a6 weighs less than a convertible TT?... it does) and I've been thinking of a diet methods.

 

I won't be able to bypass the N75 until I can get my wideband back from a buddy, AND be able to buy the SS Crimp tool that is required to reclamp these hoses. Even then, I don't know what the stock ECU will do with the added boost.

If you just try to bypass the N75, the car will only run on wastegate pressure, which I have no idea what that is. If I bypass the N75 with a manual Dual Ball Bearing Boost controller, I will raise the boost 1psi at a time and watch the wideband to see what is happening. I am sure the stock settings for the ECU are really rich, just for the added protection, so there might be some room to play with.

As for weight reduction, the simple things I did will deffinately help you, as well as an often overlooked thing-Lightweight Wheels!

I agree, you should have some room to play with a normal boost controller. There is a program called lemmiwinks which allows you to make small tweeks to the stock ECU. I've never used it, but read about some people who use it to raise boost and equalize fuel tables. I don't think its powerful enough to build a full on custom tune, but for an extra few psi it could be very useful.

 

A tuning program called "Lemmiwinks"? Jesus Christ-Mr. Slave... lol

 

Dueces give information about weight reduction is help to me. So I tale you thanks you very much. When Weigh reduction means vehicle average increase so, it is profit of economic.

Hi
As in earlier comments ,experts said that you can reduce weight of Audi by removing covers from doors etc.Yeah it's possible to reduce Audi's weight but you will have to throw the luxury material and install cheap and light stuff .
If someone has better suggestion then post it.
