1. the 74mm TB can be installed without tune or CAI.
2. the 74mm TB can be installed WITH CAI and no tune.
3. the 74mm TB can be install with both CAI and tune.
The guesstimation on #3 is about 20 HP, I have seen NO hard dyno documentation on this ....
I did it in this order :
1. installed the CAI - ran 3 months
2. installed the 74mm TB - ran 6 months
3. Got the EuroTune.
