Question about Turbo Electric Performance Fan

Hi,



my friend wants to buy this high power fan "turbo kit":



http://www.ebay.com/itm/BMW-Turbo-El...dc3a44&vxp=mtr



for his M3 E46 SMG, in the description it says that it is capable od 3.5 PSI, reading some forums it says that he will not have to tune the ECU "more than 4 PSI he must" for this to work propperly, my question is:



1. can this kit improve the perfomance of the engine? if so by how much HP from stock?



2. if he installs it, does the ECU has to be tuned?



3. is it any harm to the engine to install this?



thanks.
