I don't see "cold air intake" on your list, so I would start there. If you just forgot to put it in your list then disregard the rest of this post...

The more modifications you do that make the car breathe easier, the more necessary some form of aftermarket intake is going to be. On a totally stock car, adding the CAI is usually good for 10ish horse, and dynos I've seen on the boards show a ton of torque picked up everywhere.

If you've made it easier for your engine to breathe on the exhaust side with LTs and a full exhaust, then adding the CAI could possibly be good for 15ish horse, and tons of torque everywhere. Maybe that's all the difference you're expecting?

Just an idea! lol

^^ that's what i was gonna say. if you have opened up the exhaust but still have stock intake, all it wants is some more air... you will notice the difference for sure. but as stated above, if you HAVE freed up the intake and just forgot to list it, disregard.

get some type of data logger such as Datamaster EE and use it...........make sure you dont have timing being pulled out by a false knock signal.......also get a Wideband and check your AFR it should be around 12.7-12.9..........ive seen alot of LT cars with headers run around 11.3 with stock tunes and they turn into stoves because of it.........

Well i Have ram air with a k&n filter so im sure thats good enough... could a intake manifold oil leak cause the car to lose any power?

You don't say but with the 4.10 you're a M6 right? Generally manuals don't ET as well as autos. Your 104 trap speed looks good to me for your mods and if you had a A4 you would be in the low 13s. Trap speed=HP

FWIW I have similar mods to you and I don't trap 104 but I feel my car runs great.

Every time I get in my car to go to the track I always end up thinkIng "damn car feels slow, maybe something's wrong", but then I end up clicking off the same times as normal. You just get used to it, it's part of the sickness that keeps men wanting MORE POWERRRR!!!

What was the weather like when you raced? Elevation, DA, wind, humidity all play a role. With a 104 trap I wouldn't think your far off for your mods
