need some help. Why is mph low

1/4 12.530
mph 108.61
race weight 3750

mods in sig

It launched nice and hard. Anyone got any ideas why the mph is so low. This is a cammed car, so shouldn't the mph be higher? Should I be a little quicker too?

get rid of the ported MAF.

That looks like a decent MPH for a stalled A4, esp. considering the car's weight.

I think that is a great time for the mph. I can't break 12.6 and I have a bigger cam and trap 113. I think that you are doing good, but I am sure you want more. I am severely disappointed in my car, but hopefully with an intake, gears, clutch and sticky tires I will do a little better. I would be happy with a 12.5 but I guess it is all relative.

For both of you cammed guys, I gained 3 mph trap speeds with the LS6 intake swap and pulley. I have the tr224 and it really woke up with the better intake. This just happened last week, I wish I would have swapped the intake sooner.
