Maybe more power??

I will be taking delivery of a 94 E36 M3 this week and despite knowing that its already quick...I might want to up the std power output.I am currently driving a lighter Opel TS (181kw/352nm)..and hope that the heavier M(210kw/320nm) wont be sluggish in comparison.
What is the best entry level power upgrade available ???
You can mail me if you know who might be able to offer it in Cape town...Are the DASTEK systems any good??
Let us know thanks, Lance
