Mark D Chip vs Dinan?

I have an E34 M5 with a Dinan chip in it. Has anybody done a comparison between a Mark D and a Dinan chip for this era of M5. From what info I can find it sounds like the Mark D chip is better but before I drop $250 on one I wanted to see how much better and if it is worth it. Thanks

Don't know too much about Chips, but I've read a lot of topics about them, Long story short most people would say for the most part chips serve the same purpose, and don't make much of a noticeable difference/gain, but some argue that it does give better low end torque,redline, revlimiter, MPG etc.. Which I don't doubt at all.

My suggestion: Most people would say save your money for a better mod, but I think Dinan is quite reputable and high quality, but if the Mark D is more in your budget buy it and tell us how it goes !

I have a E39 and so does my good friend, we are about to buy the Confortti Shark Injector by Jim Confortti since he gets a good deal on them from private seller, not sure if they have those for E34 (pretty sure they do) might want to look into that as well

Goodluck with your decision !

Going from a Dinan chip to a Mark D chip will make no noticeable power difference at all. Save your money!

But on a side note, I am always curious about the definition of "better"!

MarkD tunes are fantastic. The best part is his incredible service because he's local. If something doesn't feel right, or you want a change... it's very easy to do while-you-wait. Your car especially since MarkD personally owns 2 E34 M5's. He's perfected that tune!

Dinan software:

Max HP Gain 37@ 7000 rpm
Max Torque Gain 36 lb/ft @ 3500 rpm
Peak HP 342 @ 6800 rpm
Peak Torque 294 lb/ft @ 4000 rpm

Can someone post Mark D's stats so the buyer can compare?

Remember he already has the Dinan software, he's asking if he should get rid of it for the new Mark D (EAT) software.

I have Mark D software on my M5, i'm happy with it. Mark has 2 daily M5's, like EMPOWERED said, he has perfected that tune.
p.s. Don't expect it to pull like an E46 M3 because of a chip.

Thanks for the feedback....while I'm not looking for any real overall hp increase I would like to smooth out the power curve as the car feels pretty flat until about 3800rpm, then it seems the power just pours on like a rocket all the way up to 7K. Some of the research I've done indicates that this is a characteristic of the Dinan tunes and more research seems to indicate that a Mark D tune provides a broader, smoother torque curve. Was just curious to see if anyone could confirm this or back up this information. Thanks.
PS-The M5 is parked for now but in the spring I'm thinking it might be time to pick up a chip from Mark D.

I can back it up, Mark D tune does smoothen to torque curve.
