Hi there i have a 99 1.8t a4 and i really wanted to get the giac chip and a diverter valve but i'm affraid of the car having 94k on it that it might screw up the car. This is my first audi and i really have a lot to learn but i was curious what i should do? I have all records for the car the cylinder head was replaced, timing belt, water pump, timing belt update, it uses mobile 1 synthetic oil, so i mean the car has been takin care of but wanted to make sure that i'd be ok. Thanks

 

I wonder why the cylinder head was replaced? Adding more boost to your engine obviously causes more strain. However, I don't think you'll have any problems. As long as the car has been properly maintained you should be fine. My car had less than 30K on it when I chipped it so i really can't relate. Hopefully someone will chime in that has chipped a higher mileage A4. Good luck!

 

I'm sure you'll be fine. I know people (me) who have been chipped for 100k miles with no engine problems.

 

I have 144kilometers witch is I think 70 miles around there and I ahve done a BT setup little problems here and there but you have to expect that when doing this kind of upgrade the engine is strong like bull haha running 22psi

 

As long as you keep your car well maintaned, you will be fine.
