    the MarkD Summer 2011 chip sale

    What's better than a Group Buy? A sale where you don't have to put your name on a list for a certain number of people to commit, that's what. So if you want a genuine MarkD chip for your BMW, head over to read the details and order!

    Thanks,

        All for this, I am curious as well. I wouldn't mind some more power out of my NVm50 before I go turbo.

          I have not seen any review of the 40x (402, 403, 405) chip recently but it works fine. I've been selling those for over 10 years.

          Peak gains are around 17 hp on 91 octane, @ 5500 rpm.

              What about a chip for an OBD1 M52 w/ S52 cams in an E30? Offered over the counter in that type of setup? New whip has one and might want to re-tune it but not set on that. Wanted to check all the options out there. Not sure why I am even considering it but my friend Steve has a 91 318iS and he got your chip and he grabbed 2nd hard and broke his transmission so these chips must be legit! Too much powah!

                  Yes I have a chip for the 153 DME, 91 octane and stock injectors available now. Email if you want it, I have not added it to my site yet.

                    I have an M50nv chip from Mark (403 iirc) and can highly recommend it.
                    I don't know about the power gain, but the curves are so much different, so much better than the original ones, I love it! Finally got rid of of that annoying power jump aroud 4K rpm. Now the engine pulls smoothly, but powerfully from the bottom all the way up.

                            Hi Mark,

                            Never received information on how to pay for the chip.


                            My 1989 e30 s52 Touring... this is Betty

                            My 1989 325i vert (sold)...this is Nina

                            My 1991 M5 (sold)... this is Veronica

                              PM'ed you last week about building me a chip for a SuperEta short-block mated to a ported 885 2.5i head with a bumped-up cam. Haven't heard back. Thanks.
