how hard is it on these cars to be running aem cold box, hks high power CBE? I will be getting it tuned in the spring, but i was thinking of adding a high flow cat as well. Should i wait and get it tuned first or will adding a HFC be bad for the car?

The X's factory tune is awfully rich. I know I've seen Michael @ETS mention the ETS intake is tested with no tune and will not harm the X. Obviously the more mods you do the more you can dip into that rich tune. I would think you would be fine, but I suggest anyone with a turbo car that wants to mod run a wideband a/f gauge all the time. IMO it's more important that boost, egt, and fuel pressure. In fact, about the only time something would go wrong that you wouldn't see strange stuff start to happen on a wideband if it's oil pressure loss.

Turbo Gas: Wideband, Oil Press, Boost.
Turbo Diesel: Boost, Oil Press, EGT (and trans temp if you tow)

Ive been running AEM CAI on my 11 GSR since 600 miles no issue even with season changing.
ETS recirc DP and HFC sitting in my floor at home only because im waiting on the DSG A pillar pod for my gauge solution and my cbe to come in. boost gauge and wideband are good to have just to make sure your not over boosting and your a/f is good.

not planning one getting tune until i get 3port, wga, bov ,IC ,uicp, and licp.

adding air flow usually requires no tune, unless you come into issue, its good to have the gauges to help identify issue if you have them.

I'm running aem cold box. It has a bigger MAF inlet. It will lean the car out.
but what your asking is that if you should add the parts before the tune, answer its yes because if you get it tuned first then add parts later it will throw the tune out of place. Add your parts now, but lay Off the pedal. Its not recommended that you go wide open throttle at this time because you will run the risk of over boosting and leaning.

i could be wrong but AEM is running stock size MAF housing or mabye mine was just special.

Nope CLIPSE says that my cold air intake (AEM cold air intake, cold box) has a bigger housing. Can cause of up to 10% lean on fuel trim of if not tuned and your heavy on the throttle.

thanks for the replies, i am in the midst of buying a UICP, 3 port, wideband. And then when i get more cash, i will be buying tactrix, evoscan, ecuflash and hopefully a high flow cat then getting clipse3gt to do me up an e tune. Those were the parts that he reccomended for me.
