Hey, I was checking out www.bmwe34.net and they say a Jim Conforti chip would give me 43 hp and 21 trq .... what kind of gains would a MarkD chip give me? And does anyone on here have an MarkD chip in an e34 535i and could tell me what kind of difference it makes?

I hear mark's chip has good gains, and is very comparable to the conforti.

I have installed Marks chips in customer cars including the e34 535i, the difference between the stock and Marks is quite noticeable. The m30 pulls stronger and of course longer if you bump up the rev limit. You do notice a significant difference in all the gears especially the lower ones.

I think the e34 m30 gains are much more using Marks chips compared to some of the older BMW engines.

My M5 was chipped by MarkD last fall.
No regrets!
Haven't had a chance to test if the top speed limiter has been removed yet;)!
