X5M performance and handling mods?

[AVB-AMG]

bcredliner:

I have a 2016 BMW X5M that I picked up at the BMW Performance Delivery Center in Greenville, SC this past June.

I am leasing my X5M for 3 years. According to my friends at BMW USA in Montville, NJ, most X5M's and X6M's in the northeast USA are leased and not purchased new. That may explain why many of the original "owners" are hesitant, reluctant or just plain against paying for any performance modifications that could invalidate their lease agreement, let alone spending money that they will not recoup at the end of their lease. A strong incentive to keep our vehicles essentially stock.

It is my experience that it is the group of 2nd Owner's who purchase these type of performance vehicles that are coming off of a lease who then will spend the money on various performance modifications and improvments, including coding, chips, exhausts, suspension, etc.

Thanks for the input. I have done an owner's choice lease in the past and may be the route I go with X5M. Going to dealer tomorrow to pick up some parts and get some input there. Happy New Year!

Well, I have the last gen 2010 e70 X5M and my mods are as follows: Active Autowerkes stage 2+ tune with Active Autowerkes downpipes, ADV1 22" wheels; ADV5.2 MV2 SL in Matte bronze, exposed black hardware and Gunmetal barrels, H&R 1.2" sport springs designed for EDC suspension, OEM BMW M performance front carbon spoiler, Vorsteiner replica Carbon fiber Diffuser and Dimisa 3.5" slanted/staggared stainless steel tips, LCI LED headlights and LCI taillight conversion....







Enjoy!!!

I've got an '11 x5m with pureturbos, velos downpipes, supposedly a Velos tune(-that sucks), V1, H&R lowering springs w/EDC, 22" Vossens, tint, gloss black front grills, painted to match reflectors (ft & rr), Carbon side markers and I'm probably missing a few things...

Thus far, it sounds like Dinan is the best value (HP/TQ gain per dollar spent). I will know what the results will be and it is all matched for other components. As I have done with my 4.6 I would add Meth injection system and a shot of nitrous. What's the flaw in that thinking?

You said, "Dinan". That's the flaw. My setup has nothing to do with Dinan and I would only buy Dinan components if it was the very last resort. Put as nicely as possible... Dinan is on the far left end of the spectrum. My build is far right. Dinan is fine for those who want to send a lot with minimal results and factory warranty. I willing to spend, but I actually want real high results. Not for the faint at heart... If you think Dinan in the best value (hp/tq) then I wish you the best with them, but encourage you to do more research. Each their own... After being around BMWs for nearly 20 years. I've seen the good and bad of Dinan. Dinan is not for me.

My 4.6 was Dinanized in 2002. In 2012 I added meth injection and 150 shot of nitrous. I didn't change the tune since most of my driving is without nitrous. I have had no problem.

Realizing Dinan is usually somewhat conservative, unless input and research uncovers another route where I can have over 800+HP all the time I am guessing I can go the same route as I did with my 4.6., have the Dinan tune with meth and the Nitrous add-on if needed. I think an X5M would be a good candidate for two stage system.

I have no intention of being conservative. I like to get someplace different and where most think I am an idiot for going there.

We share that in common. I must have misread your initial post, assuming you were another blanket Dinan fan. I see I was incorrect.

I'm currently interested in getting my stage 3 running right with catless DPs and stage 1 Turbo upgrade.

NOS would be down the line for me, if I went that route in addition.

My driving use would be similar to yours with the addition of a couple track days.

You mentioned a check valve you added to the meth line near the intake to avoid drip, can you explain in better detail and include the part you used?

TIA

Depending how the meth injection is installed it should not be necessary though it doesn't hurt to make sure you are getting meth when you aren't asking for it. What controller are you using? Snow Performance | The Water-Methanol Injection Experts
