I'm interested in getting Burger's JB4 w/boost control for my '11 x5m with upgraded Turbos and catless downpipes. Explain please, why Burger is shady. I've already made the mistake of buying from Omar @Velos...

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...

And why is that? I have lots of their stuff on both my X5 and my 335 N54. They've been more than wonderful for years now. I think you'd be hard pressed to find a BMW tuner who's working harder to unlock these cars SAFELY. They're not like a Cobb who's tuning dozens of cars...

That's what I thought too... After spending $3,415 and ~$2,250 of that for my "Custom Dyno Tune" the remaining for catless DPs, last August 2016... The most I've received to date is a self admitted "Base(modest) M5 PureTurbo Tune". I have called repeatedly, emailed to the point Omar says he won't email and to call. ALL without any real support or even having one called returned... I've setup 2 private 'dyno days' to the tune(pun intended) of $550 additional without the help of Velos or Omar. Last month I finally asked for a refund several times and never receive a satisfactory response to this date. Every time I call I get varying responses ALL end with me not getting to, talk to Omar. "He's out to lunch", "he's on a plane"x2, "he's not here", etc... Each time asking for him to call me back, leaving my name and number. Which if my memory serves me, he's never called me back once. I won't even get into how bad the emails are... Yeah, I guess now I see how safe they are. So safe, they just refuse to tune my truck. I have track slips and dyno sheets to prove my claims. After spending $~8k, I've gained 60wtq and 100whp. It's pathetic... I would have been better off going stage 2 Velos, but question if my experience would have been any better.

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
