Default would a nx ntercooler kit for stock TMIC need tuning?

I'm conteplating getting this kit knowing its good for 20-25 whp for our stis w/ a stock TMIC. I was wondering, would installing this kit require any tuning, or is it kind of like a "press the button when you need the power" type thing? Does anyone have this kit, and if so what are your results and thoughts about the mod? Thanks.

It's always advisable to check your AFR. If you have read other threads bickering about this issue, some say the only power gains are due to the fact the engine is ingesting the nitrous. But w/ any mod that increases power, it may affect your AFR.

W/ personal experience, the cars I have tuned on the dyno using the intercooler COOLERS, the air/fuel ratios were mildly affected and towards the leaner side. Nothing bad enough to change anything as far as fuel map. But on couple Honda/Acura's we sprayed the NX Cooler and got good gains.. But what was more awesome, was that it took almost 3 runs later to get the intake air temp back to PRE-cooler run. We were only using a 70-80mph fan infront of the cars. I am only stating what I have seen. I am sure other people have completely differant opinions/views as I do. But that is why we are all here.

Considering i'm running and AP stage 2, my afr's are a little on the rich side, so leaning it out a little w/ much cooler temps shouldn't hurt anything *i think*

The original ads for the i/c bar sited a 50whp gain on some turbo honda, but the nitrous went through the i/c core and into the engine bay, where the intake filter ingested it, causing a signifigant power gain(not to mention an unsafe lean condition). I haven't heard of it going from the tmic to the intake, but it would still probably be a good idea to use C02 instead of N20, just in case.

It would be pretty hard if one was still using the factory airbox. But the gas nitrous goes through the intercooler fins and then is can be sucked up by the air filter. IT would be easier for this to happen if you have an exposed filter like w/ a short ram. But I am not a person, in previous long-drawn-out threads about this topic, that has disputed the actual gains of the intercooler chillers and/or why the gains happened. (But it is a possiblity, to how diluted and the effect of the nitrous is still unknown from what I have seen, specially in Subarus).

So is this kit a waste of money, or does it really help temps and increase hp. I've heard 20whp and about .2 off the quarter as the average gains. Is this reasonable, because here in FL, we can always use lower temps.

the n20 being sucked into the intake is internet-legend BS. Someone used c02 and got the same gains.

its a total waste, I had one. It shoots over top of the intercooler hardly cooling it (topmount) it needs to shoot down through the fins to do anything. Its BS but looks cool.

if you have heatsoak, yes i guess it would make a signifigant diffrence....
if you are getting walked by a 911 and expect it to be the, "magic hp button...." you will most likely be disapointed.....

i'd consider it to be like the standard sti water spray but times 3....
