Dear all ,I am planning to install sc kit on my e90 n52b25. I have done a lot of research by web and tuning shop.only one company is produce sc kit for e90 which is Arma ( from taiwan )This kit can boost the 218hp to 290hp, but the problem is so many and scandal and bad news and this kits.I got no choice , since this is the unique kit for my e90.I am willing to try on it. I am asking them to send taiwan technical during installation.I will install this kit on Bm World Motor Works.The cost of sending technical is SGD 1500, for my case special offer SGD 1000.Actually I hope they can provide FOC for my case since I can be a frontier to try on their kits ( no good review only complain )I also telling them i am from BMW CLUB MALAYSIA , a lot of potential SC kit bimmer but no one willing to try.Finally they agree to reduce to SGD500 since Bimmer of Malaysia are quiet on Sc kit.I need all SIFU help. please show them the power of Malaysia Bimmer.http://www.armaspeed.com/eng/goods.php?act=cat&no=22link for this kit.
