Just bought an A4 avant 03, had it a week. need to know which chip is better.

Have a 5 hour demo on the revo. Great power, enjoying the ride, but make s a light metalic noise when I accelerate.. he said it was normal and it was the turbo.. is that right ?

I have to still spend the $200 to get sps 2 for it.

APR has a special this month where you don't pay for the ability to covert to stock. So i save $200.

But I have no idea which one is better. Each one says they're better.

Any recomendations.

Thanks in Advance.
