What are you searching for, exactly? I just googled and found plenty of CAIs for N52-powered E90s.

If you want performance software that I can flash into your ECU, just contact me. The proper way to gain power is from within the ECU, not with add-ons.

What year is the car?

$350 if MS43 or earlier
$435 if MS45 as that requires removal from the car to program

MS45 is in some 2003's and then up to 2005

No I don't sell ECU's. (the only ones I may sell in the future are MS41 328i ECU's)

You would have to ship it to me.

All non FI e90's can gain roughly 7 to 8% more torque, and the end of season special price is $500 for 323's, $550 for 328i's and 330i's.

You must have a piggyback processor, don't think that can't be detected.

As per this thread,

http://www.e90post.com/forums/showthread.php?t=382656

Apparently the 323i can be tuned to 233hp (before cat removal) because it is essentially a detuned euro 325i

Honestly if you're looking for performance why oh why did you buy a 323??? Why didn't you buy the 330 or 335? The amount of money you will spend to add hp here and there will cost way more, and I mean WAY more than the premium for purchasing the more powerful car to begin with. Not to mention if that isn't enough power then you could add the same upgrades to those and gain even more! Too many people buy the base model and say it was all I could afford or I'll modify it and so on without really thinking about it. If you can't afford it, don't buy it. Buy last generations top model instead of the current generations bottom model and be way better off.

SELL YOUR CAR, AND BUY THE ONE YOU SHOULD'VE BOUGHT FROM THE BEGINING!
