Well i go to the track very often, sometimes twice a week since it's like 5 mins away, but i have seen some trap 109 with light mods, matter of fact my friend has a 01 that has gone 13.0@ 109 with gutted cats, lid, and a4, on goodyear radials, weather was good and cool, it happens,.....
now bone stock off the showroom floor, i doubt they will run in the 12's, like most of us have seen also, some seem to run in the 14.0 103 area and cant go faster to save their lives
.
Some of these guys are porting their own maf's, and of course you wont know it by looking under the hood, but it gives a healthy gain, almost as well as an aftermarket one would.
A cuttout can gain 2-4 mph on these cars, at least they must, because a quiet ls1 can trap 105, and a "stock" ls1 with a cuttout can go 109, hard to tell, noone tells the truth, wel...i do...
