I was not going to bother replying but figured it best to give our view on your comments.
Just thought I would post this up just incase someone else is trying to tune a VW T5 AXD/ AXE and doesn't want to spend a fortune.
INSERT ANYONE BUT DARKSIDE PRODUCT HERE.
Also did a rolling road day to compare to other T5's

Also had it put on two independant dyno's:-
I know you keep advertising that manifold you run but then on the T5 forum mention it keeps cracking?
We have over 100 emails from you over the last 2 years asking all manner of questions, then you buy the parts locally or from other supplier. I have no problem with people saving money but do the research yourself too!
Please study both of your graphs and then look at ours.
Dyno Dynamics have a correction factor for the engine cylinder count. With any dyno, even set up EXACTLY the same, no two can really be compared. That's why these RR days are a good equaliser, as long as the operator is not biased....
Now back to looking at the graphs, you can see ALL of the 5 cylinder engines are run in Shoot6F mode BUT according to DynoDynamics, Shoot6 or 6F are for 6 cylinder engines. We have done quite a bit of testing using the different modes (back to back on the same car within minutes of each other) and the difference can be quite large, 5-10% extra power and torque depending on which mode. I can produce the graphs if anyone cares to see. The 'F' at the end just denotes a FAST pull despite what DynoDynamics say, power is usually identical and if tuned well, torque exactly the same too.
Usually a STANDARD 2.5 PD130 or PD174 in Shoot 4F will make around the stock power, so on a 6F pull will make MORE than rated power, so I see no reason why we needed to run in 6F on the T5.
I'd rather the customer see a realistic graph rather than an inflated one.
Its a shame we never ran the T5 we did recently on a 6F pull, I would expect 290hp+ and 475lbs. Its back over in Ireland now so sadly cannot be easily brought back to test or attend the dyno days you have mentioned.
One thing to note is the peak figures on your graph may be slightly higher but power and torque are less almost everywhere else.
Thanks guys, it seems one of the big forum sponsors starting with the letters "D" doesn't like my van as they have just banned me from there Facebook page after I said a couple of comments on there, nothing rude at all, they obviously don't like other people doing as well if not better.
Our Facebook page is not the place to advertise other individuals / companies products. If you stand outside McDonald's dressed as the KFC Colonel, I'm sure you will be asked to move along. Deleting posts is better than a public argument, but after we removed them you continued to post and had 'friends' join in, so a ban is not really unjustified. It was not me personally that deleted or banned you, but clearly the person who did deemed the action appropriate, and now seeing these posts, I would agree.
sexy curve! turbos seems to be really best compromise between low and top end, like just maxing out stock injectors. I've seen the forum sponsors attempt with GTB and 50% injectors made actually less power and more smoke.. somehow
Ruben, I did not realise you know the lambda value or saw the vehicle run on the dyno and road? Less power? Read above.
Its a shame you decided to take such an aggressive attitude towards me. We all started at the bottom, don't ever forget that. I'm thankful for all the help everyone gave at the start.
I know of two other guys on the T5 forum with the forum sponsors GTB kit on there 2.5's and they didn't make any more power over a well built hybrid turbo that costs far less.
It shows people don't do there research because if they looked on the T5 forum they would see you can get the same power for less spend, the 3 top vans at our rolling road day last week made 266hp, 283hp and 287hp and none of them are running a full GTB turbo.
Neither of those Vans you mention came here for tuning (if we are thinking of the same vehicles), one I know for sure had more issues with the van and tuner than anything else. Again not a fair comparison if none with a GTB were tuned here.
Our customers want a quality kit, tuned well, at an established company with all the right equipment. Price is not their main concern. If you can afford the premium brand you won't go to the scrapyard for parts, or likely have the time to! If you want to do it all yourself to save some money, no problem. Just don't attack a company because you can't afford their products.
