Question about "Power pack"

[ikatoro192]

Sorry maybe many times similar topic. I knew T-Pack and S-Pack but relatively new "Power Pack" offered for new Elise TRD Airbox + Filter, Stage 1 Sports Exhaust some say it's more torque and power increase 7.6hp. I am just wondering this additional power comes from airbox and filter or also exhaust if this is the case TRD Airbox + filter and 2bular sports exhaust (I am thinking 8"x 22") is same thing isn't it? oh and without ECU remap?
thanks for advice.
cheers

'Power Pack' is just a term made up by one of the dealers as an aftermarket add on to a Toyota engined car.
TRD and a decent exhaust(not a Lotus one but a 2bular, Larini etc)will give small gains but more importantly a bit of character/sound.
The ECU will learn automatically so no adjustment required.

I go for it then.
