Hi guys,
I was BNR tuned for about 4 years. Jerry kept telling me that I had a boost leak when I would expect an update. I spent over a year and 100+ data logs trying to find this mysterious boost leak. I decided to take the car to a local dyno tuner to diagnose where this boost leak is coming from.
Mods at the time were:
BNR tuned
BNR FPCM
BNR WGA
stock turbo
ZZP downpipe
ZZP intercooler
Ported intake manifold
AEM intake
GFB bypass valve
42 Bosch green injectors
MSD coil pack
Straight E85
Here are the dyno results and analysis from my local dyno tuner:
My dyno tuner, Kye, basically said it runs like junk because the tune is garbage.
So no boost leak and 143HP! I gave Jerry the results and he said that dynos are off by up to 110HP and no updates until I had to ask for them separately, dull KR sensor and increase timing. Jerry took over a month for these two basic updates with minimal improvement.
Not long after, I started burning oil but I don't think it was tune related and I did a complete rebuild (pretty sure just the turbo oil seals gone). I installed a ZZP V3 turbo and valve springs during the rebuild and refreshed the entire motor.
I sent Jerry a log and no update other than telling me how bad chinese turbo castings are. I sent him another log and no update but he did say there's a boost leak again. This took over a month and still no update for my new turbo build. Because the boost was spiking and hitting overboost super easy I had to learn how to tune it myself so I bought the HPTuners MPVI3. In a couple of weeks, I managed to control the boost spike so I could drive the car. I sent Jerry another log and he said they can't edit the tune now as I have edited it. And there lies the death of BNR and the misery of unlimited free retunes for new parts.
I couldn't optimize the tune at all myself so I finally got the tune from Tim at ZZP. What a legend. I'm installing the ZZP cam upgrade now as BNR don't know how to tune for cams.
I haven't dyno'd yet, but it's a beast and still more to go with the cams.
Muz...
