I plan on keeping this 335 for quite some time, so price point is not at all a factor for a tune that would be backed lock stock and barrel by a BMW dealer as you say.

Excellent info Mo - I'll check that list out this week!

What does PPK have to do with 335is?

PPK wouldn't work on 335is

335is already has PPK

PPK is a way for other 335i to get to 335is power only without 8 sec turbo boost

PPK is conservatively rated
320 hp 332 tq
Dealer can tell you anything

Dinan is perhaps slightly overrated
355 hp 401 tq
Could be involved in dispute between Bmw and dinan without a loaner car in process

Doesn't mean dinan is bad
Just PPK has a lot of good value

I own PPK

Have not tried dinan

Anyone with n55 PPK
Upgrade to dinan 2?

What's this all about? What happened?

BMW N. America will not allow the PPK on any non sport model 335i. You have to have certain options apparently. I've called BMWNA and been to 2 dealerships. They put in my VIN and they said no. Since I don't have the oil cooler and a certain sport package.

Kenny, are you serious with your post?????

I can't even respond but it did make me laugh so kodo's. You need to read some more articles about torque and horsepower. They are not correlated my friend. More importantly, build an engine. Their are many variables that one can design and build into and engine depending on $$$ and desired usage. Rally, dragstrip, oval, etc.

I race an M3 and that car is proof of that point!

You can have a high or low torque engine with similair horsepower ratings.

Are you serious?

Your comment was that dinan makes the same torque as other tunes, but les hp.

Since you race cars, can you explain how, on the same car, you tune a car for the same torque, but less hp at the same rpm?

Hp = torque x rpm / 5250

Looking forward to your response.

[D's Bimmer]

The equation is reference to a static formula used to quantify horsepower in relation to torque. The reason why two tunes with identical torque can and most often due have different power output is because the characteristics of the respective tunes have different peak horsepower. For example, tune A may achieve its peak horsepower at 4700 rpm while tune B doesn't achieve it's peak output until 5400 rpm. This is the value that a tuner can deliver in terms of creating a time that meets the driver's requirements. In addition, a tuner can and often puts covenants, restrictive code, etc to create the optimal balance they are looking to achieve. If you read my note gain, that is exactly what I said.

The custom tune we created for my M3 has very high torque with governed peak horsepower. The reason for this is the same used by Dinan actually. The stress load put on the cars drivetrain and other core parts could not handle the power load over long durations. This would lead to material car damage and a shortened life of parts.

You can't simply add 25% more power to a car like this and not be expected to reengineer the drive train. So if two tunes quote te same torque and their horsepower is programmed to peak at the same rpm, the output will be the same. But the reason there re so many different tune options is that people needs tunes for different purposes and designing the correct power flow at the right rpm band is what makes the difference.

[Black Gold]

Half of that has nothing to do with the original question.

Again, you said dinan has the same torque but less horsepower.

At the same given rpm, that is impossible.

If your point is that dinan tapers boost up top earlier than te other tunes, but is equal at lower rpms, that's one thing (although I don't think the second part of that is true either)

On two cars that are the same that have the same torque at the same rpm, the power must be identical and cannot be different. If one car has more hp at a given rpm than another car, it must have more torque as well at that specific rpm.

On topic : I'm nt that impressed with the dinan dyno curves I've seen. The two I've seen made less than quoted hp and torque (using a 20% correction to crank hp)

After much drama and 6 weeks of waiting, I had the stage 2 PPK installed on my non-sport 335.

Guess who's gettin a DINAN flash Friday?

I don't have option code 840 on my 335 so therefore BMW WILL NOT do the ppk on my vehicle. Like I said before... it goes by VIN. Am I making this stuff up? Ask the dealer like I did on the stipulations. But, good for you that you had it done... you obviously have the option code that mine does not have.

NICE!! Who are you getting it done by? A BMW dealer or Motor Works West?

I'm sure this goes without saying and is on everyones mind, but PLEASE let us know your thoughts ! All these PPK/Dinan threads are making me itch to jump on the bandwagon as well, so I'd love to hear what you think about the difference between the PPK 1 and the Dinan Stage 2.

Thanks!

[D's Bimmer]

That's great. I love what it has done to my car from a performance and drivability standpoint. Look forward to hearing your thoughts after it is flashed.

Congrats!!!!

Prestige in Ramsey. I have you SOLELY to thank for this Mo. You are truly the man.

[Dark_Knight_335]

I will keep everyone posted. VERY stoked.

Happy for ya man. Go to a drag strip or dyno after too I want to see the capabilities of the dinan tune

Thanks my brotha! You are an inspiration to all of us N55'ers. Thank you!

+1 thanks everyone for your thoughts and inputs. its def helping me make a decision!

[Dark_Knight_335]

The gains are great, but the warranty and peace of mind alone that you can walk into any BMW dealer and be covered for four whole years is fantastic to me.

No, I most assuredly do not have option code 840, which is why it was such a pain in the ass to get the stage 2 PPK installed. I don't think you're making anything up either.

As far as I know, I have the only base model 335i(non sport, non option code 840) to get the stage 2 PPK.

Yea... no idea why I'm not granted access to the PPK. Ah well. I'm very happy with my Dinan tune

Have a good one!

Thanks buddy... but no praise needed. Just did lots of reading and talking with the Dinan people. Enjoy it!!
