So looking at getting the ZZP BWv3 turbo. Thoughts on a ZZP tune vs BNR tune please. I'm BNR tuned atm but not sure if they'll deliver with the ZZP BWv3. BNR said I'll need the FPCM for more fuel pressure with the 42# injectors, ZZP don't need this mod to tune it. Also BNR said that they won't tune past 19 PSI because ZZP won't honour any warranty over 19 PSI and I have to agree to BNR not being liable in any damage over 19 PSI. ZZP said this isn't true and they had honoured every warranty to date (a few months ago). So yeah, not sure on how to proceed with tuning...

Oh really? @Thebigzeus might find this interesting.

As for warranties and customer service go, ZZP is top notch from my experiences. BNR probably just wants you to buy their products. Which is understandable, they are a business. Especially since apparently they don't charge for additional tuning or so I'm told.

My tuner charged me $350 to re-tune for my build.

Yeah they were selling their turbo over ZZP, but I couldn't find all the results that apparently show all the HP advantages...

I'm currently running 22-23ish PSI on the stock turbo too...

 

[Muz]

I would really like to stay with BNR for tuning, just uncertain given the circumstances. I want more than 19 PSI, lol...

 

[Muz]

My 42# injectors are running about 60%, should be enough for much more power. I mean it's fair to buy a bit of product to contribute to the re-tune, but if I have to buy a FPCM to make it happen then so be it. If I can trust in the BNR re-tune then that'll be the best option. Need more than 19 PSI though, lol...

 

[Muz]

i'm tuned with BNR, have the ZZP V3 turbo and tuned to 23-24 PSI. that said, i also have 60 LBS injectors (from BNR) it runs really rich at full throttle.

it could be just me, but i have had nothing but good service from BNR.

Did you have to specify going over 19 PSI or not?

 

[Muz]

i never specified. i just sent logs and asked if there is room for more to bump it up a bit.

How did you find the change to the ZZP BWv3?

 

[Muz]

it took a couple summers for me to get where the car is at now. if you drive a 2011, to go to higher than 19PSI boost you'll need to update you Map sensor.

Really? I haven't heard that before...

 

[Muz]

I'm hoping to see some direct comparisons of someone who has had both BNR and ZZP tunes. I'm actually quite tempted to get ZZP tuned just to compare to BNR. Just don't want to fork out for a different tune to find out it's not as good 🤷‍♂️

 

[Muz]

That's probably RARE. I don't see many people spending $800+ on tuning.

Yeah, ZZP results are few and far between. Not sure where all the BNR tuned dyno's are. BNR told me the BNR GTX250 will produce 230-250whp on 93 octane pump gas, with the ZZP turbo making 200WHP on E85. Is this accurate or just pushing their numbers for marketing? I have only seen one dyno recently with the GTX making 177.25 HP other than BNR's dyno's on their website. Comments on that were that it's not accurate 🤷‍♂️

 

[Muz]

Are you on the BNR performance closed group facebook? There are some posted there.

Thanks for the info, I'll be checking them out. Lol, funny though that BNR said to look at non-ZZP owned threads for an accurate comparison, so yeah still unsure of any accuracies and what not...

But yeah been a member there for ages...

 

[Muz]

Yeah I'm not confident on the BNR dyno's. The main reason I want the BWv3 is the increased flow through the turbo/exhaust housing. Doesn't look like I can increase this without having to re-cast the housing/exhaust manifold. Was thinking of getting a tool in there to port it out but it doesn't look possible. Looks like the biggest restriction in the little 1.4T. The exhaust can't keep up at all with the intake flow from what it looks like.
200HP on pump gas looks good to me, just wish there were many dyno results to support all the claims...

 

[Muz]

Yep cool, that's what I got from it too...
