I dont know about my audi Ive only had that going 115 so far. But its much more fun takeing my vette to higher speeds

 

I did around 128mph in my audi before it was chipped havnt tested it since not enough road out here

But hey I did 120 in my old K5 blazer with only two leafs left of my rear suspension and a whole in the floor large enough to lose a small dog through talk about a rush that might have been kinda dumb though...huh?

 

Ive had my audi a4 doing around 125 to 130 not all sure cuz i had my eyes on the road with just airfilter and exhaust but had to slow down for corner, does anyone know about how fast they will top out when chipped. 50hp/52ftpt increase?

 

I've had my S4 touch 140 for a brief moment; I got too nervous to go faster. It was an open road, with no other autos, but I'd rather wait for a closed circuit to find out the truth behind my S4's top end.
