TCU is the Transmission control unit. You meant TS ECU. And no, TS isn't the answer 100%... It is a cookie cutter. It's best to 'fine' tune (higher resolution) the AFR w/ an AFC.
More air is always good, but if it's not dealt with correctly, it can hurt power.

A few technicalities here:
1.) I never said a loss. I mentioned 'hurt'. Which IMO, means inconsistent performance and/or not working to its full potential.
2.) You mentioned loss, which I would imagine you mean a loss in peak power. Peak power means nothing, since the area under the curve is what's important.
3.) If we want tog et technical, that link with the dyno in it showed a loss of 1 ft/lb. Whereas with some caressing of certain parameters (tuning). It could have raised the tq in the + range and significantly (8+) raise more whp, depending on what the AFR curve looks like.

It also depends on how far you want to go etc.

Also, what are people avaraging in terms of MPG increase. From what I have read, people get an increase of .5-1MPG.

Not to say ECU mods will not come at some point but thats later on when warranty is a thing of a past. Till then, the sound is very satisfying even if that's all the CAI gives me at this point which I highly doubt.

It's not the mod, it's the ECU, these parts (UPD, CAI, Catbacks, headers, etc) are solid performers if tuned correctly...
After I put my car on the Dyno for tuning, the first pull was 243whp, tuned, next pull 249whp, tuned, last pull 256whp.

Ive been thru all this with an 06 Mustang gt, if you put a CAI on you have to reflash the ecu on those. My understanding on the Maximas is they have a more flexible ecu than Fords, but i think intakes and exhausts would mandate a dyno tuning and reflash to get the benefit of the mods. Nissan is getting 300 hp out of the 350z with just tuning and exhaust changes, so the power is there to be tapped. I was looking at the Injen sp1946 cai, they claim no reflash necessary, but only a marginal hp gain so not really worth the bother. I will probably leave my car bone stock because its not a racer and i dont want to have issues with warranty and the dealer over mods. I am waiting for a much higher hp 350z to come out in another year or two, they will probably be revamping the car soon and who knows maybe a V8? Something that will smoke Vettes would be sweet, i will trade my Max on one of those. Till then the mod bug can wait.

Odds are the question you're asking is in the links. Also, when all else fails,
