Try to compare to this MHD PS2 OTS. There is a load target that is actually being followed quite precisely and boost target is adjusted along the way to do this. https://datazap.me/u/harkes/ps2-ots-...a=3-5-10-11-16

Fearing to start a war here but that 2H looks very crude and hasn't improved since I stopped using it ~2 years ago.

PS: Not saying that the MHD is perfect - cause it also has its issues, but I think these are more related to PWG in general that is just a B*TCH to tune.

PPS: I consider my custom tune "finished" (will drive it for a few weeks to see if anything to tweak). Work done by Fabian from PureBoost and he was the only person of 3 "high profile" tuners that managed to make a working tune for my car. Biggest issue I still have is the post shift overboost but it seems to be either that or a dip in performance which I can feel in the car.

The flat boost target is characteristic of BM3 OTS maps. That's the way it is in almost all of them. As you know, it does not have a load target and determine boost target based on that, unlike MHD. The fixed, flat boost target is what makes the tune unable to adjust for weather (i.e., HPFP crash in winter on BM3 ethanol maps) rather than adjusting based on atmospheric conditions.

Yeah, the maps underboost to get better timing, though I had some 94 oct left in the tank and looks like it wasn't enough lol.

here's a fix:

It ran better later on during the track as it was still adapting, but it needs some work. I don't plan on getting a custom tune until I get my hands on a DE HPFP.

Guys, who has an experience with cheaper options for DV+?
Like these $30.99

Choosing between GFB for $120 and like that one for $31.

I got my GFB DV+ for sale for 60$, it's just missing a extended bolt.

Not sure i would buy a cheap knock off DV given the difficulty of the install and the fact that its a moving part and not just a pipe. But if you test do report back.

I don’t think I notice any difference. I go the vent to air version. I was able to goto track last night and got some logs. I posted in racing forum. But here is one run. I logged it leading up to and a bit after to see what else was going on but you can zoom in on the details.

Is this the before or after?

Update:

I was sent a replacement unit to replace the one I have, and after testing, the old one I had had a defective solenoid cable, we just sent the entire old unit back and replaced it, now everything works, no codes, no nothing, just whoosh sounds!

Nice, thanks for the update. I am currently testing the CTS intake and there is SO much whoosh sound even with stock DV. Review and comparison on that + dinan + OEM MPPK setup coming soon after i finish logging tomorrow!

Here's a 91 oct log, BM3 has a bug with the new update I think, so it's written as 93, but it's actually 91. 2nd gear is all fudged up because I had xDelete on and I spun all of 2nd gear doing a log starting at 2500rpm, fishtailed everywhere lol.


As you can see, WGDC is about 10% less than DV+ or stock DV, I believe Pureturbos even advertised between 10-20% less WGDC as well for the Turbosmart. I had between 61-68% WGDC using the same map with the DV+, it also looks like AFR is very stable as well, hell this BOV literally fixed most of my OTS map problems. I actually recommend this over DV+ for sure, and if you run custom, I'm sure with the reduced WGDC, you can probably squeeze out a bit more boost.

I am still in shock of how shitty that 91 must be when I can run +16psi with better timing on 93... Also dont understand why BM3 dont lower timing or boost to get rid of that all that correction... Looks messy.

These are PWG WGDC numbers though right, so what do you think for EWG? I would find it hard to believe if DV upgrade alone changes WGDC by more than like 3% on a EWG, but i could be wrong... Maybe that will be the next thing to test after intakes lol...

Honestly, I think it would be a 5-10% difference, the turbosmart holds boost much better and I believe you might not overboost much on EWG as it's not vacuum, but I think it'll help with holding boost through shifts, plus you don't need to do maintenance on it like the DV+

I know we're both speculating, but ive seen EWG logs for people running the turbosmart, albeit not back to back with a stock DV baseline, and i recall the changes being very hard to see, maybe 1-3% lower WGDC. 5-10% decrease from just a DV upgrade on a EWG would be insane, and i would buy one right now.

Anyone have datalogs on the same tune with EWG before and after DV upgrade?

I think pureturbos advertised between 10-20% lower WGDC, so maybe with a upgraded turbo there may be a much bigger difference?

Those are EWG numbers? Where'd you read that? You're getting me a little hyped even though i dont think even 5% is achievable for just DV upgrade on a OTS map, but i will highly consider ordering the TS DV if it goes on sale for black friday to confirm or deny this theory. Would just like to see some data before then.

So a EWG car with a working OEM DV going to a TS DV would see significantly less improvement. But hey, maybe i am just a pessimist.

You never know, I think there might be a legit improvement over stock and DV+

sub'd. Planning on purchasing a pure stage 2 kit on black friday and deciding between the DV+ and TS EM BOV. Interested to hear if the version pure is posting about is the recirc version or VTA. For what its worth I had a pneumatic BOV on my last car that had a factory ECU operated recirc valve and that caused no AFR issues. The pneumatic BOV was a PITA though in terms of throttle response, ECU controlled BOVs are definitely the way to go. My current take is that the easier install of the TS EM BOV, slightly better throttle response, and need to lubricate the DV+ every year or so is well worth the extra $135 for the TS BOV. Interested to hear everyone else's thoughts though. It seems like I have a much clearer choice than those of you who already have the DV+ installed on your vehicle and are facing the decision on whether it is worth swapping out or not.

As you mentioned, i think your choice is clear - get the TS. Although it hasn't been around as long as the DV+, so the long term data doesn't necessarily exist yet, I don't think there's been a single report that the DV+ is better than the TS; everyone seems to report the opposite. I haven't purchased either yet, but if i do buy one, it will be the TS.

After running the CTS intake for a bit (see my intake review thread), there's no way i would get a VTA BOV given how loud the recirc is with a non-closed box intake. Potential concerns with dumping metered air aside, the noise would have to be excessive and i would be worried it would get old fast, unless you are specifically seeking that. It's funny because with the CTS intake, i keep wondering what it would sound like with no DV and a bunch of compressor surge lol.
