Is your car full weight?

How high are you shifting with the ms3?

however, if he put down 401rwhp, that car isn't going to trap 118-120 at his weight. i would expect maybe 116 at best, but 400rwhp is 400rwhp, it will propel the car at the same speed, whether it is through a 9" or a 10 bolt.
do you have a dynograph we can see, 35thls1? perhaps after we know where you're shifting we can help..
also, the weather would make a difference, but it took 94* temps and 99% humidity to knock my car down 2 mph in the 1/4. over a 75* and 35% humidity comparison...and i'm still on the stock tune.

I think so especially if the other guy is keeping his engine in the power band more through out the 1/4 mile.

Ur A/F could use some tweaking IMHO. Add some fuel down low and in the midrange, this will improve your TQ. Your definatley rich up top, you could pick up some hp by leaning it out some. Your 12.5 from 4500ish to 7k.
With this said it's not gonna improve your trap by 6 mph though. Your results seem similar to my buddys cammed car. Dynos well, 430/408, but doesn't perform down the 1320. He ran a best of 12.73@115, 2.1 60ft. This was with a TSP Torquer II.
For comparison I am running 12.5s@111-112, on 1.9-2.0 60fts with only exhaust, lid, and my own ported TB.
