Well, I finally got my Dinantronics tune installed this past Monday. My car already had the "old" MPPK (mechanical wastegate) on it, so my Dinan tune is an MPPK "stackable" version. My initial driving impressions are that the car definitely pulls harder and feels more explosive. Furthermore, I did not experience any of the low end delay or lag that a few other members have mentioned with the Dinan tune. Instead, it actually feels more responsive with the slightest press of the throttle. Sport+ mode with shifter to the left feels phenomenal. It also continues to feel smooth and rather linear all the way to redline. There is no drop-off or any of the other issues I've heard experienced with other tunes.....no need to shift early or anything. As weird as this sounds, it feels almost as though the shifts are even faster (though that might be placebo effect because of the added power). It definitely makes the car feel more "M-ish"....although I'm sure it is still far from the feeling of a new F80 M3 haha!

To me, it is definitely worth the money, not only because of the peace of mind with the warranty aspect.....but also because I truly believe that the engineering involved with Dinan products makes a difference. Everything is smooth, snappy, and linear.....but now my organs are squashed against the seat even more so with every push of the throttle.

I had it dynoed this morning on the same machine that I had my "before"results measured on (and very similar conditions.....65 degrees and rainy). Here are the #s:

Before: 304 WHP and 308 lb-ft (wheels)

After: 330 WHP and 352.2 lb-ft (wheels)

Very impressive increases for a stage 1 tune in my opinion! Anyway, thought I'd share. Feel free to chime in if you're thinking of this tune and want further feedback/opinions.

Nice results but that's like $3000 for same performance of bms stage 1 for $379. I know that includes the BMW warranty on the Mppk and the Dinan rider warranty coverage on the stage 1 but hey, what ever make you sleep easy at night.

Cool. Results are a little better than others who have put it on the dyno.

Post the graphs.

I would never suggest spending $3000 on both the MPPK and the Dinan. In my situation, I kind of had the MPPK on the car from the start, so it was essentially part of the purchase price and I never thought of it as an out of pocket extra expense (even though it was in a sense). Now two years later, I felt like it was time to upgrade, thus the Dinan. And....I might add that I waited until I could save a few $$ on the Dinan until now....my Dinan dealer is running a promotion of free install, so I saved there too.

The argument over Dinan vs JB4 has been beat to death (and each has its pros and cons). I merely wanted to chime in on my dyno readings since there's relatively little info out there on the Dinantronics and the power it puts out.

Fair enough, and very nice results.

So with just a Dinan stage 1 tune (No MPPK), I could expect similar results?

Nice gains.

Will do....a little later when I have a chance.

BMS dyno'd Dinan stage 1 with aFe intake on an M235i (320 crank) and got only 313 WHP. So you can figure out what you'll get on your 300 crank x35i.

What Dyno brand were you on? Mustang? Dynojet? Dynapack?
Mustang is the most conservative of the bunch and is usually soul crusher with regards to numbers.

Dynojet.

Dyno Dynamics is the worst I've ever used. Read about 80whp lower than a DynoJet on my Jeep. Either must've been slipping or they're really, really, bad.

Any idea what the "new" MPPK numbers would be (before and after Dinan)? I have 2014 with the "new" MPPK (also came with the car as in your situation) and looking to stack something on top...

Dyno's are a weird instrument. So many factors (temp, humidity, etc.) affect your numbers.
I've been on every brand except a dynojet.
Dyno Dynamics usually read in the middle from my experience. Perhaps the one you used wasn't calibrated or in need of service.
Dynapack's read super high in torque.
Mustang's just crush your soul with their low readings.
If you hit 400+WHP on a mustang you're kicking lots of ass on the streets.

Good torque curve.

No off boost issues then. How is the turbo lag? Better, worse or no different from previous?

I don't know about your before #s, but I'm guessing your after numbers would be the same hp (approx 330 WHP) and your torque would be about 10-15 lb-ft higher than mine.

Turbo lag seems a touch better than before (meaning, less lag).

[Damon44]

I realize that horsepower is listed in various ways. You listed whp in your test.
According to the Dinan website when they added their
Piggyback tune to a MPPk configured N55 they came up with 360 hp and nearly 430 foot pounds torque.
Can someone tell me why such a big difference?
I also had my MPPk installed at the port in December so I have no stock engine responses to compare.
The plain MPPk is supposed to give me 330 hp with nothing added.
Are you implying Dinantronics added nothing?

[Buckeyes]

Depending on the type of dyno, dynojet, mustang(heartbreaker) etc results can vary greatly. Add in the other factors like temp, heat soak, density altitude, number of pulls, all effect the numbers. Finally switching from wheel horsepower to crank, again, changes the numbers. The reason dinan states crank numbers is because it's the bigger, more impressive number that has been corrected for drivetrain hp loss. It's a meaningless number. Rear wheel horsepower it the actual horsepoweR the car is putting down on the pavement.

In the end, a dyno is just a tool to have a before and after comparison to see how a tune or mod made a difference. Even then, it needs to be the same dyno, similar weather condition, and ideally, the same guy running the dyno to get an accurate result.

Yeah....due to 12% drivetrain loss (probably about right for a Dynojet), the actual crank #s for my dyno reading are 375 hp and 400 lb-ft of torque.

My torque is the only thing that seems to be a tad low compared to the Dinan claims (they claim 417 for my car)....but I'm very happy with the hp. The dip in torque could possibly be attributed to the fact that I have a catback exhaust, which sometimes causes torque to go down a hair.

[Dosturbos]

Numbers are just numbers, if the car feels stronger, pulls hard and puts a smile on your face, that's all that matters.

Nope, it can't.
