i have the same chip, if its for a 93-95 325, it takes off the rev limiter, new speed of 264 ISH, and around 211BHP over stock, not too sure about the tourque!!!
its a GREAT BUY, i suggest it to anyone that has the right specs, best BANG FOR YOUR BUCK if you will!!!
the thing is, you need to have the same MODS or the chip wont work, meaning if you have cams or flywheels, that are performance, unless the original owner had em, the chip won't work, so do your homework!!
