Hi Manufacture figure for 0-62 mpgh of my car (S4 automatic) is 8.3 sesconds ..far behind the manual's 6.8 With the new chips I clocked it my self and the result is around 8 seconds..I think with high performance chips . It should one it in around 7 sec. Do yo think 8 is normal for 270 hp. ? Why it isn't much faster than stock. thanks
