The stock engine programming operates within a range, so it has to adjust for different ambient temperatures, altitudes, humidity, etc. However, if you add a good set of intercoolers, you can then also reprogram the ECU to adjust that operating range, add even more fuel, and thus generate more power. In all of our testing, we have never seen IAT's rise over 110 degrees F, and that's the in the middle of summer here. That's just one of the ways intercoolers help.
The other way is by allowing a greater flow of air. Especially when the car is programmed and running higher boost levels, the intercooler is also asked to flow a much greater amount of charged air through it. The factory intercoolers are 3" thick and have 15 rows of cooling passages for air to flow through. Our intercoolers are 4.5" thick and have 18 rows of cooling passages. If you want to get REALLY technical, each cooling passages on our intercoolers is also about .5mm wider the stock, so over those 18 rows, you also have about 9mm total of extra passage.
Hope that explanation sort of helped...maybe a little at least.

Please don't worry so much Tom. I'm not into keyboard fighting really....but can't answer for others who have sustained a little damage to inflated ego.

Colder (or cooler) intake air temperatures are always a benefit. Cooler air is more dense and contains more oxygen then warmer air. So when cooler air is sent into the combustion chamber of your engine, it allows the engine management to introduce more fuel into the mixture, which in turn creates more power.

My question is if I leave my tune stock will the new coolers and tube add or subtract anything? Or is it just for better engine health on a stock tune car?

No I never say that. But it is clear to even novice like me that Tom know much more than you so sorry to dent up your ego about that point. On this occasion of your opinion about EP and Tubi it seems you not even know enough about EP having a 100 cat so on what basis do you form a judgement to yourself, least of all pass opinion in an advise form to SDG what he is best to do????

Isn't better a subjective way to say something. Sound BETTER, FLOW BETTER...all depends on what 1 wants I imagine

Okay then. But I was really hoping you will have some more expert advise to offer but it looks to now all get down to just take your opinion that something is better than something else without you even knowing anything about it at all? Hmm. That is a really funny way of advise giving. Anyway...peace to you.

Well, been surfing forums for around 15 years and I learn that the "keyboard figths" like Tom said is not worth hundred of words of explaining or awnsering questions about products that I'm not relate in any way (just that I install them and have a positive or negative result). Lot of info of good and bad products I share in a few forums and always it goes both ways whem members post they feedback, it's normal that they relate with some brands for any reason.
I just go with the flow hehehe and if somebody want to doubt my knowledge about cars, I just let it be
