Hey all,

Here are all of my mods, Dinan II Rev 2, Dinan Front/Rear Sway Bars, Dinan Exhaust, KW V2. The Dynos, CDV Delete Mod and the KW V2 were done at PandL Motorsports in Franklin Park, IL and they did great job!

BTW, if any of you were thinking about getting the KW V2's, just get it, it's absolutely amazing!

Can you just post your peak #'s? I (and probably others) can't dload/view the pdf at work. Also, did they measure boost as I'd be interested to see the curve?
Last, what progman did you have going in, and do you notice a difference in any sense of turbo lag from before and after the flash?

Sorry, but I didn't have a boost guage to measure the amount of boost. I dunno which program I have and as far as lag is concerned, I really don't notice any lag at all, so maybe I don't have the 29.2version.

I wouldn't expect you to watch and log your own boost...I figured the dyno might have had the hookup to log it.

are those numbers on par w/ what they are supposed to be?

that would put the crank HP around 355-360 right?

Dinan's orginal press release for what is now Stage 2 was 384 at the crank and 342 at the wheels around 5700 rpm with 11.3 PSI at that peak.

If I had Dinan's tune I would want to run a boost gauge to make sure I got the stage I paid for.

FWIW they also showed 392 Crank HP/350 WHP with their catback (including xpipe).

I would hope most customers are seeing 330-340 whp with stage 2 and an otherwise stock car.

for comparison, I ran 347whp I believe on just Procede V2 at 12.5psi and the Helix intercooler. stock tune was 286whpw the intercooler. I believe 12.5psi is lower than the Dinan II tune? Scott, I thought the Dinan II tune was around 13psi?

It just seems a bit low to me.

The PSI for the Dinan stage 2 tune is 13.2 PSI...

[OpenFlash]

Two things I don't understand:

1) How that tune can be rated for 385bhp
2) How it makes such little power for the boost pressure it is purported to run.

Has anyone ever verified boost pressure with a boost gauge? Or shown Dinan or any of their reps a dyno sheet and asked where the missing 25whp is?

I think it may be an issue of purposes restricting horsepower in Stg 1 and 2 so they can give an appreciable bump in power with $tg 3. But even then, the bhp claims are fraudulent.

Now I understand that many Dinan customers aren't all about dyno numbers and quarter-mile performance. And that's okay. But when you pay a couple to a few thousand dollars for a claimed power output, shouldn't you get it? Or something close to it at least?

Shiv

yup....hopefully the OP can pop on a boost gauge and at least verify the Psi is where it should be. If he's only running at 10psi........

Just want to make sure people are getting what they pay for.

312whp seems very low for 13psi especially with Dinan's coveted exhaust. Maybe that dyno reads very low.

typically a Dynojet will read high....but they can all be calibrated differently. Really need a baseline.


However, this is not the 1st recent Dinan dyno that looked low.

If it was just one dyno result, this could be the case. But I don't think I've seen any Dinan dyno result live up to the bhp claim. Granted, everyone has a different sensitivity to money expenditure. But asking $1750 for muffler replacements, $2000 for a flash and then more for labor, oil cooler (if necessary), etc,. is pretty gutsy when you're giving back 40-50whp more power with no outstanding improvements to driveability for functionality.

That's a wildly unsubstantiated claim. You should know better than anyone that dyno runs without baselines are useless for gauging BHP at the crank.

When 95% of all cars, on all dynojets, dyno between 270-280whp. And 95% of all the Dinan cars, on all dynojets, dyno between 310-330, conclusions can be substantiated pretty well. Also, there were a few people on this forum that have posted before/after results on the same car, same dyno. Maybe not same day, but that would be logistically difficult.

I have been questioning my dyno results as well. On the original stage II flash I dynoed 320rwhp and 379rwtq on 91 Octane. I redynoed on the same dyno different day with the Stage II rev 2 and dynoed 309rwhp and 382rwtq on 91 Octane. Keep in mind my car is completley stock except for the tune. The second dyno the temp was significantly hotter than the first dyno. Temperature aside, although the torque is great the HP does not seem to be what is advertised. Unfortunatley I do not have a baseline dyno of my car and this is why I have not made a stink of it. I should be getting my boost gauge this week but it is a mechanical gauge and not a digital so I will have to have someone record it so I can try and log my peak boost. I am curious to see more dynos of the Stage II rev 2 for more comparisons.

If my 335i is baselining at 275whp and then makes 325whp with the Dinan Stage II flash, it's making pretty much exactly the crank hp Dinan claims. I'm not seeing anything fraudulent there. I do see one tuner eager to discredit a larger, much more established tuner, though.

I don't see anyone who has the Stage II Dinan Flash claiming they've been duped or ripped off, either. I suppose we should just take your completely unbiased opinion as fact, though, eh?

[Wicked_SVT]

There is one thing that is definatley shady about Dinans advertising that I noticed from the time the original flash came out compared to when the revision was released. If you look at the original press release from Dinan it states that the 384fwhp and 421fwtq was done on a completly stock car, NO EXHAUST. If you look at figure 1 in the press release it states "Figure 1. Dyno results for a stock 335i vs. Dinan 335i (software tuning only)". Now the claims in figure 2 state you get 392fwhp and 429fwtq with free flow exhaust. The press release specifically states "Figure 2. Dyno results for a stock 335i versus the Dinan 335i (software, x pipe and exhaust)".

Now lets look at what Dinan is now advertising on thier website for the Stage II rev 2 flash. The description reads "The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related recalibration along with the Dinan Free Flow Exhaust producing maximum output of 384 horsepower at 5700 rpm and 421 lb-ft torque at 4300 rpm*. " So now you mean to tell me when I purchased my original flash we were all under the impression that I would get the advertised horsepower without an exhaust. Since the revision has been released it now specifically states that the exhaust is needed to achieve the advertised HP. Now I am no lawyer but that is a little misleading if you ask me.

Don't get me wrong, I like my Dinan tune but that seems a little shady to me.

Yes, I know. But....when you hit max HP the boost has already tapered off to 11.3 PSI. Not my numbers, Dinans publication. See page 3 of the PDF.
