I got Mark D'sylva's Ultrachip installed in my M30(E34), but insurance was transferred to a different car, I haven't had a chance to test it out.

So I have a few questions, just out of curiousity.

What increase can I expect for HP/lb-ft.?

What numbers would I get for acceleration to 60 in an auto w/ sport mode engaged?

Is top end decreased/low end increased?

Thanks!

I think its one of the top two chips available for the m30 (the other being Conforti). I have it in my 535i. I don't know the numbers but I like it. Besides having to run premium it improved performance across the board.

I heard the Conforti was also very good, but the MarkD chip was cheaper. At the time, I didn't know about the Miller MAF/WAR combo, but I would have looked into it.

There is certainly a lack of accurate measurements of before and after performance for the Mark D chip in an E30. I've installed it for my M42 engine and while I notice the difference, it is small. Nonetheless the result is pleasing especially in street driving where the increased midrange torque helps noticeably. I too would like to see some measured data.

I think Mark D chip will be good and is cheaper also.
