Thanks for the replies. The explanations are logical, although I have heard some people claim greater fuel economy when the car is chipped. I plan to get mine chipped in the coming month or two.

 

This is true if you show control and not boost the crap out of it every chance you get and then some. But most likey when you first do it, you will see less cause you cant fight the urges

 

You guys are actually missing the whole history of the 1.8T engine. Originally, Audi engineers made it too well, so, they had to cripple it by using software to throttle the turbo back, cut back the rev limiter, and overall make the engine weaker. Audi wanted the 2.8 N/A to be their flagship motor, and when the original 1.8T came out packing over 220hp, they needed to change that. That is why chipped engines are just as reliable as they are stock.

 

for a b5 i would go giac or apr.... i personally have apr and love it..... someone with giac might say the same..... you will also need to upgrade your dv and there is an apr one for sale still i think http://www.audizine.com/forum/showthread.php?t=161227

 

The rev limiter has nothing to do with the stock turbo. Having it at 6800rpms vs 7500rpms makes no differnce except that you would make even less power at 7500. The turbo is actually just below the sweet spot for it at .6 or .8 bar (whatever your case may be) and a chip takes it to its outer edge of effiency and then most people take it just outside of its effiency by running it 20-22psi. And you know that the engine is far from weak, its a stout motor and can handle 300ftlbs easy.

I agree about the V6 and making it the "dominate" motor, but what can you do. The turbo 4 vs n/a 6, the n/a 6 will always lose with just a minor change in the tune.

 

I totally never said anything about the rev limiter having anything to do with the turbo. I just said that they cut it back while they were scaling everything back on that motor.

 

The point was that it doesnt affect the car in anyway since you would make less power past 6800rpms. Hell, you could move it to 6400rpms and still have little affect on the car with a stock turbo. What im saying is that the car can rev past that, but if your not making power there, whats the point in having it that far out if your making less power

 

wow guys car is designed for the audobahn first of all, most european cars are a turbo application to increase speed to the audobahn req. and for quick pulls in their style of driving. Of course if you chip the car with software programs by Revo, GIAC, APR ya the booost isnt significally substantially to damage your car unless you drive like a shmuck and over a period of time yes oem components may be at fault....Who needs a stock B7 A4 2.0t quattro 6spd OEM exhaust with 4k on it......PEACE

 

Yeah, when i think high powered german car made for the autobahn, i think a stock A4 . Thanks for playing.

Also, many euro cars are turbo'd because they use tiny motors to fit in small cars and also use as little gas as possible. A Liter of gas there is more than a gallon of gas here.

Now i want my twin charged 1.4L vw engine in my TT. only makes 120hp and 160tq from the factory, but im sure i can up that a bit. Oh, did i mention it makes over 40mpg?

 

When I think Autobahn cruiser, I look at my bosses 745iL or my friends A8L... A4's are the ones that are passed by everything on the Autobahn, except for the Fiat
