N54 Dinan stage 2 Dyno Results

BIMMERPOST
     Featured on BIMMERPOST.com
Took the car for a few dyno runs today. 316 whp.

Car has the following:
Dinan stage 2
N55 midpipe
Berk street axleback
K&N drop in filter
91 OCT gas

Conditions: 95 deg F and 18% RH. Two pulls in 4th and last pull in 3rd.

Car seems to run rich at higher rpms. Anyone have any experience with this tune?

Im happy with the numbers. Seems to be in line with advertised numbers because Dinan's claims are with 93 oct gas.

Next, and last mods, will be BMS DCI and FMIC. Will dyno after and get torque numbers at that time too.

Dinan just has 1 setting correct? For example I have cobb and can switch maps for my fmic and when I get dps I can switch to diff map and etc. I'm not a fan of dinan personally but as long as your happy that's all that matters.

I love my Dinan tune. Everyday, it works. No funny stuff. What a great daily driver.

Lot of cash for less power IMO. That's what dinan has become over the years.

That's it? 315whp? Not a very good deal at all.

To me its a good deal and thats all that matters. Dinan is conservative and thats what I wanted. I get to maintain my CPO and my goals were never to make a beast car. I wanted about 400 hp at the crank and I'm just about there. With 93oct gas I would probably already be there.

Dinan Stage 2 is $1299 now so all together I'm in $2100, or about $35 per whp. In a $40-$50k car I don't think thats unreasonable.

You can maintain cpo warranty with other tunes as well, but if you are happy with it, that's all that matters. I don't recommend riding in a cobb car as I guarantee you will switch with the quickness lol.

Sorry did not mean to offend you. Was just surprised at the dyno, thought Stage II would be a lot more based on the Dinan adds.



This was my out of the box run with the old $495 non-ISO version of the JB4. Test was run on 93 octane. I don't see moving from 91 to 93 being worth more than 8-10whp.

As long as you are happy that's what counts its your car & money, again no offense intended.

I have read threads on here about warranty work where member have said that they had to wait weeks to get repairs because bmw was saying dinan should cover a specific problem and dinan was was saying bmw should cover it. I have had my cobb tune and had the factory warranty for a year and a half with no problem. I bought my car cpo and it didn't affect warranty at all. I just found a dealer that was mod friendly.

No offense taken. Its funny when people shit on your decisions because they took a different path. Not sure why they do it...to self justify the path they took? I'm just trying to contribute to the forum because I'm not the only one who will take the Dinan route. Oh well.

That's your experience. And not something anyone should expect when they go to a BMW dealer to get service on a car modded with non factory sanctioned parts.

Exactly. I for one appreciate you putting up the info you did. I may consider a Dinan tune on top of my PPK2. I used to be the maximize horsepower for the money spent when I was younger. But with age, I have valued the priceless experience of knowing I can jump into my car and just start it without any issues. If there are, it's most likely NOT the tune or anything around it. I would like to see a comparison of how many people report issues with a PPK or Dinan tune versus a JB4 or Cobb. I know it's anecdotal but it could be some what informative.

Thanks, and I agree. This is my daily driver and can't afford to risk reliability. Bottom line is I knew what my expectations were, and they were not unrealistic. I spent many hours researching aqnd I could have made other decisions to go with a different tune, but I decided on Dinan.

I had a cracked valve cover replaced under warranty with all my mods stated above. Dealer gave me Zero shit and did the work quick and with no questions. For me that's worth money. But...YMMV.

How can you compare when one makes significantly more power than the other? Of course you will have more issues with Cobb and JB4 as opposed to Dinan mainly because with more power creates more stress to the vehicle.

The issues members are reporting that possess either Cobb or Jb4 have nothing to do with the tune itself.

If you want to get Dinan because it is more conservative (Less powerful) and is warrantied, then that's fine but you can not compare it to Cobb or JB4. IMO, Dinan is overpriced. I go by The cost to power ratio so logically the Dinan tune does not make sense to me.

Again sorry you got your feelings hurt & feel crapped upon but to post things & only expect atta-boys in response is not very realistic.

Forums are about sharing info & other choices. That said I don't see a 12.5 car @ 114mph for $495 over stock needing a whole lot of justification.

That info might benefit someone who does not have $2100 to spend & still wants above average performance.

Z-10 my antidotal story is a 2011 335is modified at 1500 miles JB4+COBB 410whp on a DynoJet; sold in 2014 to get the 435. No issues with the car or dealer service over the 3 years I had it, your results may differ.

The 135is does not have enough mileage, about 12K, to make any statement about the JB4/ISO but so far so good.

The 435 is a MPPK/MPE & will stay stock due to another car which will be the take to the strip & track day.

Be interesting to see how much of an advantage a Dinan system has over the MPPK when I can dyno it. Seems the new cars need a 4 wheel dyno even if they are 2 wheel drive & the place I have been using is only set-up for two wheel drive cars. So I need to find a new location.

Really? Seems like some double talk there.

There are those of us who want to have some additional performance but don't want to sacrifice any reliability or deal with any hassles with getting warranty work done. This piece of mind is what gets captured in the price differential everyone keeps talking about.

All I and others are saying with a JB4 or Cobb is you're not guaranteed to have hassle free warranty coverage. Just because you were able to get the dealer to do warranty repair work doesn't mean that somebody else will have that same experience. And some say the same might happen to Dinan mods but I can guarantee for every person with issues getting Dinan or BMW to own up to the problem, there are many more with a Cobb or JB4 with this problem or worse.

This reminds me of my days with the F-body GM cars. Many say LPE engines were overpriced for what they were. But they were rock solid and reliable.

I did my days of modding to the nth degree with engine work, nitrous, etc, etc. I'm done and just want a car I can enjoy without the hassles. If I want ultimate speed and the maximum adrenaline rush, I'll just take out one of my two sport bikes.

Agree warranty work depends on the dealer.

The smart one looking for repeat business work around some mods like FMIC, intake etc. They will also tell you to take it home & pull the tune before they look into other things like misfires etc.

Dealer shops looking for the higher payback of a customer pay vs the BMW warranty payout will whack you for any mods that the car.

The key is finding a mod friendly dealer. That said don't expect any dealer to go out on a limb for you on a big dollar item that BMEUSA needs to approve if they see a tune or fault codes showing that you screwed up.

Gentlemen, I can not agree with you more. I love my Dinan tune. Simply, performance with out any sacrifice. No codes, no issues, no compromises ... just get in and go and that is what my baby beast does every morning, every evening and every weekend. Everybody has their choices when it comes to modding. I think we chose the most effortless route. Some may disagree but money was never an issue for me. I just want it to work the first time around and every time afterwards and when something breaks, I can get it towed to the dealer, have it fixed and with a courtesy car to boot. Now that is service!
