Hi Guys,

BPC Stage 1 vs JR AutoTuning Performance Stage 2

I see that these both options can give you almost equal power

~ +70hp, but the price is different $799 vs $599

What is the difference? Could you please comment? Thank you.

I can't comment on BPC, but I put my JR stage 2 in just 3 days ago and it's freaking fantastic. Massive difference, insanely smooth delivery, no issues at all. Props to Jarek!

I'm running BPC stage2+, for about 2 1/2 months, and no c.e.l. and it is a viscous car. And I've been running low 12's and loving it....

[Greck]

The main question is why I have to pay $200 extra if they are the same? Why guys who have BPC paid it? For what?

[Mrdeezy]

Dude, value is subjective. They are both proven on this forum and respected. Do you homework and search. Most members here have one or the other so you will not hear many bad things about either. They both make a lot of power and have good support. If your shopping for price just go buy a JBD.

I have the JR 2+ from Alex at FixmyVW and have driven a bit over 11,000 miles with no cell or issues. It is probably more power than I'll ever need and am very satisfied.

I believe BPC is getting a bit more power on the dyno for all comparable tunes, but not sure how that translates to real performance. I believe the best 1/4 miles have come from JR based tunes, but too many aftermarket mods on each car to really compare.

Either way you are going to get an awesome tune and even better customer service. I chose the JR simply because it met my needs and I was too busy to make a trip to BPC to get a dyno tune, which is were the BPC staff seems to really shine.

Also, don't merely go off the listed tune prices. I believe both offer some type of package discount,

[robnitro]

I'm not sure about BPC, but at fixmyvw they want 150-200 more just for an x5 35d e70 tune over the same tune on e90. I think that its bs because pretty much the only extra thing on the x5's are the LP egr. I'm still not sure if I will do it yet, just checked my intake manifold and removed the flaps. The flaps have a coating but not much soot. So the egr is not that bad with the lp egr. And with my poor man's "tuning box" I'm halfway to a tune. Without the need to delete the egr or the dpf right now, I will wait until prices are more reasonable, like the tdi crowd has.

[BB_cuda]

Robnitro, Prices are about 2/3 of what they used to be ($800 vs $1300 when I got the JR stage 2 race tune). Also, lots of learning and minor fixes along the way (BPC urea level warnings) and now those are corrected. I would offer the thought that you're being offered an improved product for less.

It is a night and day difference from 3 years ago when there was only 1 emerging option at that time. No one here recommends that emerging option either. Some of us here have paid 2 different companies hunting for what would work. It's more of a sure thing now and for a greatly discounted price. The customer service from the 2 prime sources is greatly improved as compared to the other guy and his NJ affiliate.

You will be so happy and forget about the $800 when you feel the difference.

@BB_cuda, So what do you recommend and why?

Greck,
I stayed out of answering your question on purpose. Only real answer is someone who has used both tunes. My JR tune is different than the one you ask of so I honestly can't give you a one-to-one opinion. I have stage 2 race (deletes).

There was another thread asking which vendor to go with. Several of the tuned crowd all came to conclusion that either one is very good. Most of the tuned cars here have gotten the deletes (my opinion anyway). You are asking for a comparison of the tuners products where all emissions stay in place.

I was in a different quandary when I got my JR tune. I had already paid Ecotune and came away with less than we were promised. My questions were more along the lines of "will all of my problems be solved and will new ones emerge". My happy result was all yes, all problems solved and no, no new ones bubbled up.

I really can't tell you what the extra $200 buys you. Good luck.

[Nadir Point]

IMHO, when it comes to aftermarket tuning, people with these cars should just stay stock unless they are willing to go full delete. Most of the reliability issues have been emissions-related. That to me, is an all-or-nothing proposition. Anything in-between just makes things more complicated than they need to be and leaves one or another time-bombs waiting to go off.

What are the JR tuned cars running? The only JR tuned car I've seen post track data is tdiwyse but, he's using a custom fuel controller to manipulate rail pressure and to control water injection. Are there other JR cars trapping 110+?

Petey Highboost trapped 110mph with the BPC tune.

This statement isn't entirely accurate...

Not intended to be bashing, but I think the statement is 100% accurate because...

We can speculate all day long about car vs car, but there are too many variables to make a direct comparison. That said, the only car to break 12 seconds is a JR Tuned car, with far fewer mods (at the time) than many of the others (Hybrids, bigger meth, full custom exhaust, etc). That by no way means that the fastest 1/4 mile car is fastest from 30-120 or anywhere else. Traction is probably the biggest factor, then where the HP & torque is arriving in the RPM range.

But again, either tune is very impressive and we are all fortunate to have the support we have today. Makes for one hell of a fun ride

It's not accurate because you're not comparing the tunes alone. You're throwing in a highly modified one off car/ result to validate your post.

Compare a JR tune only car to a BPC tune only car. Petey ran 110mph with tune alone, no meth. What are the JR tuned only cars running in the 1/4? Have any other JR cars posted 1/4 results?

I'd bet tune vs tune you'd see very similar trap speeds.

i too believe they will be similar, but if I recall correctly, TDI's car wasn't nearly as modded as several that have tried to duplicate his times. But I probably should consider it a one off until someone can do it again.

I just need to get to the track and get a JR comparison....Tune and no other add-ons. It would be awesome to have both tunes on two DDEs to run back to back in the same car.

His car is modified beyond everyone else afaik.

-custom fuel controller that adds fuel on top of his tune and at specific RPMs. (Clearly a wicked tool)
-custom exhaust
-custom rear diffuser
-custom airbox
-custom intercooler

Are there any other JR tuned guys posting 1/4 info? Maybe tdiwyse will make a pass on fuel only for the board?! There has to be one other JR car that made it to the track. No?

I agree, head to the track. Most places run Friday and Saturday's. Go make a few passes, then post the results. It'd be cool to swap DDEs out at the track for a better comparison.

I trapped 112 a couple weeks ago on a JR stage 2 deletes (not stage 2.5 or 2+ or whatever theyre calling the second level delete tune) in about 80F weather with a headwind on a track that goes uphill, sonoma raceway.

Nice! I must've missed the post(s) where you said you went through with this modification.

As far as I know, this is the fastest and quickest 335d: http://www.e90post.com/forums/showthread.php?t=1199862

Would like to see more details about his modifications and ambient conditions (density altitude) and specifics of the track setup. He certainly benefited from a strong tail wind.

Nice. Time slip?

Aren't you running water/meth injection? Burger motorsports kit?

http://www.e90post.com/forums/showthread.php?t=961958

Petey ran 110mph WITHOUT water/meth injection and on the BPC tune only.

My point, simply stating a tuner is better than another because one person with a highly modified car and that's using a custom gadget to manipulate the computers fuel delivery is not an accurate. Tdiwyse has is car sorted and he's doing great things but it's not simply because of his tuner.

As I've said before, equivalent tunes from either tuner are going to run similar MPH in the 1/4.

I dont have a timeslip handy for trap, the only one I have is something like 93 mph because it was bracket. I did run the 112 a couple times that day though along with 111 and I think 110 once early on. Petey is also a stage 2+ he says, which is good for an additional (?) 10 hp/20 lb-ft or so over the regular stage 2? I went with the lighter tune since living in commiefornia I try to keep a slightly lower profile.

The 112 was without meth, I was still searching for a new source for meth after moving.
