try to focus the main point:
1. A tuner can’t reach my 600bhp goal:if that’s the only issue. It’s no problem for me. Because I choose myself and he really provide the custom rom. So he really provide the service for what I paid (maybe just some complaint in my mind “he’s not so good as many people’s recommendation”)
2. Why I put relationship to tuner and vendor:At the beginning, I didn’t feel anything wrong of tuner too. So from 5/14 order confirm to 5/24, I tried contact with vendor all by myself. Only on 5/18, I emailed to tuner to say sorry that I suffered such thing, so I can’t take log for a couple day.
On 5/25, I try to ask tuner for help to have a local call to vendor to check if they are still in business, So I can tell that they cheated me if they still take other guy’s call or they really suffered something not be able to go on biz if they also not take local phone call. I think asking tuner to spend 30secs to have such local call should be reasonable since he suggests the vendor.
If tuner’s feedback is “No, I can’t help that”. It’s also OK although feel not so good. But if tuner feedback like below “usually take a few months for them to set up the kit and to ship it. I wouldn’t be worried”. Would you feel strange why he seems to know that situation in advance and just try to convince me that “it’s normal, just wait a few months, don’t worry about their disappear” That’s why I feel something wrong about tuner and vendor.
Guys, ask yourself when you buy something by someone’s suggestion, the shop response quickly before pay and disappear right after pay. And you ask someone to help to check something, he replies that “don’t worry, it’s normal”. Do you feel something wrong?
Finally, I still want to repeat that “It’s a public forum, everybody can share their experience no matter good or not only if it’s true not fake”. If you disagree that, just say why and what you based on, don’t focus on other things. I delete post on FB group because the group name is “N54 upgrade turbo tuners”. It’s really too rude to say loudly something bad in tuner’s shop. Not because anything wrong in my sharing. Somebody mentioned that many good experiences of this tuner like fast reversion, it’s true, it’s positive for this tuner”. But I still feel strange that why tuner just convince me that it’s a normal situation, don’t worry. Why not just take a call to clarify what happen to the vendor? Why you seem to know that situation in advance, you don’t remind anything?
Guys, if you suffer the same situation, then you still feel normal and feel that will receive the stuff in a few month. I think you should be the crazy supporters of the tuner. But I’m a normal guy, I have common sense that what’s normal, what’s wrong. So, that’s why I share the experience here.

whole story :
Hi, everyone. All the experience is real and can be proven by message/mail/web record.
A. 2/9 get contact w/ DocVu, provide my detail mod list and ask the tunning fee, and Vu reply $350. My goal is 600bhp, about 510 whp ( that’s after lots of research, my setup should be easily to make it ). Vu initially start to introduce prometh and pi meth……
[fig 1-6]
B. From 2/9~ 4/17, I do a lot research again to check if I really have to do PI meth to meet my goal, and my conclusion is “No”. During this period, I also do my maintenance, including brand new index12 injectors, dephi coils, and 2 colder 020gap spark.
C. 4/17 I decides to choose DocVu by most people on FB recommendation. After I paid $350 by paypal, Vu ask to pay more $100 (because he doesn’t notice I’m 17t) + $20 (because I don’t use “gift” function in paypal, actually I don’t have gift function in paypal). But I still choose to accept it just ask him to have a no-meth version for free, and that’s deal.
[fig 7-9]
D. From 4/17 to 5/1, after 5 revisions, Vu said that’s the result of my setup. During the process, I solve my compressor pulley issue. And Vu keep asking prometh and overdrive and 3.5bar(I had it) to more psi. I used virtual dyno and dyno log to check the power curve and simulate the dyno (about 450whp, 650nm), and will do the real dyno.
[fig 10-12]
E. 5/6 have the sad dyno result (blue/red for rev4/5), about 450whp and 650nm. Pretty close to the virtual tools. I ask to more improvement because many guys can easily over 500whp by 17t/93oct/meth, even the stock turbo.
[fig 13]
F. From 5/7 to 5/11, Vu ask to take my own charge pipe meth risk and start more than 20psi tuning. After 5 revision w/ meth% from 70 to 90, still mix cyl misfires. Since Vu try to do that but fail, I made my decision to go prometh as Vu suggestion. And Vu said that w/ prometh I can hit 550whp.
[fig 14]
G. From 5/12 to 5/24, I start to check my orginal snow kit fittable w/ prometh Rodney. Prometh always answer my question quickly after a couple hour. And I ordered the kit on 5/14. Just after my order, I wish to confirm my nozzle spec to them but they disappear. Regardless customer service, phone, email, FB, ig… They just disappear. I also ask for help on FB group, and also have the same case which is cheated by prometh.
[fig 15-18]
H. 5/24 I ask help to Vu calling Prometh to make sure if they are still in business. ( Prometh local biz time in Cal. is my local time 23:30 to 08:00, and I still try several times to call them ). To my big surprise, Vu said prometh usually take a few months to prepare the kit…. WTF, that really make me question about the relationship between Vu and prometh. If that’s long time required to do the preparation, prometh should have statement before order. Even though not, they don’t need to hide…. So by common sense, they are cheating me.

Till now Prometh still not ship out. Do the sharing to all, hope that will help for those seeking etuner.
