performance chip

Hi, can some one help me with what type of chip i should buy for my car please i have a 1990 525i. i want to get more power out of it. thanks Mark.

The Mark D'Sylvia chip will give you the best bang for your buck. I'm pretty sure it runs at two-hundred. There is also a Jim Conforti chip thats a little more expensive... three-fifty? This gives you a little bit better low end. Just look at the specs and raves on their sites.

thanks for your reply,i've been in touch with Mark D'Sylvia and all is good. regards Mark.
