Ok so now I have gone 171, NOT FUN ANYMORE.....
The car started to move around a little too much for any kind of comfort.

 

165 IM MY 2006 A4 compleetly stock down to the paper filter

 

I truly believe we all have a death wish...

 

Governed at 158

They go well over 160 with just a minor tune

 

The stock tune that was pulled by HPTuners shows 155. I did 158 when it was stock. Fastest to date was 175 and pulling like a SOB. Procharged GTO.

 

The limiter is 155. Any reading higher than that is speedo error.

Very easy to change though.

I've had mine up to 150+ one time on the street. Had it up to 141 at Memphis on the straight away before turn 1. That was when I was only making 368rwhp, should go a little better with 70rwhp more
