I was just wondering if anyone could chime in and give some feedback.

It appears The Jarek tune is less expensive. And they seem to be further ahead with the egr shut off and the scr removal tidbits. They now offer USA support.

BPC seems to have higher / monsterous dyno numbers. And is catching up with the emissions deletes quickly.


Any other positive information or experiences anyone can share to sway a potential customer either way?

I researched both and found them comparable, but the USD has strengthened some since my research. I would have had to ship the ECU to Jarek, whereas I could drive to BPC. The international express delivery equalized the costs, so I chose the more local option. After I had already pulled the trigger, I did see that Jarek teamed up with a US distributor.

BPC did me right. I did the deletes and replaced the red charge pipe at the same time. I am very happy with the power and the mpg improvement.

I don't know how you can say that "Jarek is further ahead with EGR shutoff and SCR tidbits". You might want to read some of the most recent reviews of the BPC tunes.

I am more than happy with my BPC tune.

[HeatherM35d]

BPC customer service is un-matched.. That's most important

[QUIKDZL]

+1. BPC just tuned my car with all emissions hardware intact, and defeating the EGR with the tune. It's awesome. See my Clean Stage 2 Tune thread.

[shnaggs]

Have not dealt with JR so can't comment on that, but BPC was great to deal with, great customer service!!!

My god, you've started a war!

I've been comparing the two. The dyno graphs aren't really directly comparable. The few pm I've received say that JR is a little faster in races but not by much. Basically given the same hardware both perform similarly. Probably both are based on the same tune and use the same 3rd party tools, as it's unlikely either company had the computer science expertise and hardware to break the dde encryption . Typicaly a 3rd party company cracks the encryption and rewrites the code, and let's the tunes customize it using their tools.

Basically I'd say on the same hardware they perform similarly. JRs tunes are significantly less expensive and have a several years of shelf life.

BPC seems to have excellent support and a lot,of,participation on the forums. However there haven't been a lot of cars racking up a ton of miles yet on bpc tunes.

Both offer full deletes and hybrid turbos

Bpc seems to deal better with the stock turbos and the over spool issue.

JR has good support if you email them. Too me it's a toss up, both are good options.

[Mrdeezy]

Thanks for all the info guys. It is very confusing on who to pick. They both seem very good. I don't really believe in shopping strictly on price. I would want the more reliable tuner. Would probably need support at some point. Also, if I ever needed a revision for meth or turbos that would be great as well. I think for a lot of us newer owners, Its very difficult to differentiate between the two.

thanks again
jajaja!!

+1 for most of this....Glad this discussion has stayed somewhat civil

Many do appreciate the interaction with Bob on the forum, myself included. And it looks like JR's distributor AARodriguez just joined as a vendor so no doubt we'll be hearing more from him and he'll be providing support as well.

JR does have the advantage of being out longer to prove the reliability of their tunes but BPC's are plenty reliable so far from what their customers are saying.

Not sure regarding the comment of the stock turbos and over spool, as JR's tunes deal with the stock turbos just fine without any issues.....Hope you're not basing that comment on my car's modifications lol

And yes, just because Jarek isn't on the forum as much doesn't mean there isn't support, he (and his distributor now) has always been willing to stand behind his product post sale for issues and/or upgrades.

The decision is a tough one because they both offer great products

I'll be a tester for BPC, this week. I steered to BPC for a few reasons - no international shipping, no customs. Recommended on the forum. Very good communication so far. I wish the price was lower; I wish we had the OBDII programming through the OBDII port. It's nice to see they can program for every style, apparently.

This does not belong to me in any way.
But still it is not fair to compare like this.
You are not able to check in any way, how the work is done and probably you don't even understand though you see it.

So, then comparing is only, I feel, my opinion, great, like ....
Unnecessary thread.

[Yozh]

Glad that this did not turn into a sausage fest...

I'm sure a few of us old-timers can attest to some of our painful experiences with a downpipe that did not fit and a tune that did not turn off EGR and kept spraying urea mixing with soot. That was in the past with a tuner that we so really wanted to succeed.

Let's be glad that we now have two good sources with great refined tunes that work, great hardware, customer support and great companies that are willing to support us in our projects.

Lots of great BPC and JR feedback. Personally, I've been running JR for over 1.5 years and it has been perfect and problem free from day one. Did I mention: No Codes.....

JR's tune is available in the Atlanta metro area as of the new year with his new US distributor. Just thought you should know.

I agree with 'tiki hut' on this one..this thread is pointless, just here to start some huge battle and have people fuming over top their keyboards

Seriously, give props to both JR and BPC. They have put a lot of resources and effort to map their tunes for this car. Remember only about 10,000 335d's were imported. How many of those are still active, and then how many of those will be tuned? This is a very small and niche car, not to mentioned its out of production. The logical decision would have been to ignored the M57 and concentrate efforts on the N57. Next up will be the B47 (4 cylinder) & B57 (6 cylinder) next generation diesels.

Great job by JR and BPC!

[WreckerX5d]

You really can't go wrong with either option.

[Puerto Rican 335d]

I have RENNtech's programming and the alphabet soup deleted and car has been running excellently for the past 3-4 yrs since its programming, the only down fall I've had was the crank pulley breaking but besides that I hv had no codes and no problems, to say that one or the other is better than each other is like saying which brand of beer you like. Jr has been able to amass a great following and now we have a newcomer , we've waited for 5 yrs and finally we're moving forward. I've decided to stay where im at cause for ONE I don't do the drag strip and two I like leaving aholes behind with what I got. Lets be happy and enjoy these two guys

You are correct that most probably wouldn't understand what is actually done in the tuning, but that doesn't really matter to most people. The end result is what's most important.......Forum members should be able to ask who prefers what and why as the OP did and get some well-balanced answers, experiences and relevant facts without a vendor bash. Isn't that the point of a forum?

And see, when members give a little thought to what they type on their keyboards we can have a civil discussion and there's no need for anyone to get pissed

[rulonger]

We can compare costs
We can discuss which services either provides - mechanical install, delete, meth, etc
We can share our experiences about customer service from A or B
We can share our joy with the results from A or B

And I am unsure if there is anybody that has run both tunes, so comparability is difficult.

But I see this as very positive - there are two viable options and each shop has some very satisfied customers. They both make the d community better. And that makes the choice harder.

A hat tip to both A and B

[Mark M]

The bigger question in my mind is what is the 'base tune' used? Was it originally a tune from a Euro M57 that has been tweaked for our US cars? If so, many of the more sophisticated US OBD codes and safeguards likely don't exist to give the driver ample warning of a problem, such as a clogged DPF or other factors that affect the health of the mechanical systems. Call me skeptical, but I am inquisitive of this for a reason.

[Nadir Point]

I believe the "base tune" as you refer to it, would be whatever is contained in the DDE you send to them.

I'm not so sure that's true which is why I was putting this question out to the two maestros.
