I'm at about 1000 miles on my 2012 that was delivered with the PPK. If this is better throttle response then I'm glad I had it installed. Part of it may be the difference in how the throttle map is programmed on the DCT vs 6sp cars, but mine still seems like it takes significantly more pedal travel to get the same response. While I don't miss the DCT, I do miss the extra throttle sensitivity when sport mode was turned on. Whenever I blip the throttle on a downshift, I have to press it practically to the floor to get the revs up enough. I've noticed two other things that seems a little strange as well- first is that the BOV opens around 6200 RPM in first gear so the power drops dramatically, second is that as you pass 3/4 pedal travel there is a slight surge in the power curve.

Yeah throttle response is alot better, i just press it 2/3 of the way and it hauls a55, with the old software i had to press it 3/4 just to get the car moving.

If you don't mind me asking, how much did BMW of Autin charge you for everything and how long they kept the car for?
Thanks

I had a service appointment about a month ago and which i was not happy with the results. After a month of email exchanges and expressing my disappointment, they offered me the PPK for $400 installed stating BMWNA would pay for the actual upgrade. Not sure if they did this because of my complaining or because I've been a customer for over 10 years or both. It took about 3 days because they have to order the license key for downloading the software and that comes through regular mail. If you do it make sure they have the license key already so you can have your car back that same day. Of course my pricing is a special case so I would assume they would charge $599 plus labor like others.

The recirc valve opens when you shift, otherwise it stays closed.
Also, the power band on the N54/N55 has the torque dropping quickly at bit before 6200rpm, so you're just feeling the natural power curve of the engine.

Having to floor the throttle to get a blip seems strange.
In my N54 I don't have to floor it at all, just a nice tap does nicely.

Maybe that's a condition/difference between the N54 and N55.
Can't say as I've not driven an N55.

Power surge once you're past 3/4 throttle?
Yeah, I'd say, as it should be.

Just scheduled my PPK install appointment for next week!

I doubt its the recirc valve since my foot is still flat on the floor when all of a sudden you hear the whistle and rush of air as if you had suddenly let off the throttle. Believe me, the surge isn't unappreciated it just feels a little strange since the rest of the pedal trave versus power curve feels more linear.

Hold on, dyou have a BOV or just the stock chargepipe/diverter valve setup?? Cuz this means alot here. If youre stock in that area, then an obvious whistle and woosh at high rpms WOT isnt right. Boost pressure doesnt vent to air in a diverted setup as it obviously just DIVERTS thru the manifold flowing thru the system. This is why Bov's are so much more necessary with higher boost/power levels, theres more boost pressure especially during WOT/shifts so venting to air and allowing the turbos to spool faster with less lag from existing diverted boost pressure pretty much simply allows for faster, smoother more efficient power.

Honestly thou, either way if your dv's are making that noise, get it checked. If you have a BOV setup and its releasing pressure at wot BEFORE shifting, get it checked cuz either you have a shitty BOV thats leaking or cannot handle the boost you're giving it. Period.

Just had the tune done, haven't had much time to really turn her loose. I did notice the traction control light flickering more often when I pushed it a little. I also noticed the oil temp gauge showing a little higher than normal.

On another note, they also changed the oil and performed a recall service on the computer, something about the side mirrors and windshield washer heaters. Whatever it did, I hate having to reset all my personal settings like the triple blink and doors locking when driving. Oh well. I'll give more of an update later when I have more time with the car. Its too damn cold to be outside right now.

I dyno my car before the ppk and just got it installed today... I will post results after I get it dynoed on tues... Definitely the throttle responds is better... Let see what the dyno will say....

I agree i have a much easier time rev matching with the software.

That's the same software update that neutered my car before the PPK.

Then its a good thing they did it before the PPK upgrade. Or at least I hope they did, lol. They said they would, because they didn't want something to go bad during the PPK upgrade because it needed something from that recall update.



EDIT: I just emailed my SA asking the order in which the duties were performed. Hopefully things were done right.

Very likely.

I am still bugged that I bought and had installed the original ppk just a couple of months before the electronic only version was announced. Living in Northern California and not tracking the car there is not a need for the additional cooling. I am curious if there is any deference in output between the two kits.

That said I have found a very nice bump in power. The first time the tires broke traction shifting into third I knew it had a little extra. The car felt very good before but now the right pedal holds a Pavlovian addiction quality. Driving around SF with the window open results in big grins and seriously awful gas mileage (single digit if it's a really nice day).

I look forward to seeing the before and after dyno results. Cheers, George

How much did your gas mileage decrease by? If you still drive it like a lil girly boy do you still get your original gas mileage of say 18 to 20 mpg? Or will the PPK kit make it significantly worse?

[doublevanosrc]

Just came back from a spirited drive during my lunch and i must say I'm really liking the PPK. I really got on the throttle and let it rip,a minor power gain can be felt during the first 2 gears and the exhaust burbles happen more often than before.

Anyone else feel legal speeds feel slower? On my way to my local tire shop, besides struggling to keep the car under 55mph, but the speed feels like I'm doing 30. I dunno, maybe it was me, but it feels like I'm crawling, yet my speedometer reads I'm doing the limit.

Hmm, to me legal speeds feel slower in any modern BMW especially my 1er.
