Aftermarket options - Dinan?
 

Hello all!

Anyone out there hear about any aftermarket options for the 435i xdrive? I've been checking the Dinan webpages but unfortunately there is not much available there (or seemingly anywhere else).

Dianan says early Spring for software for the F series.

i was under the impression from a youtube video that Dinan had software available for the F32 because it is the same N55 engine as the 335i but was causing a lot of trouble with the 'computer' of the 4 series or something of the sort. Dont quote me on that though.....The M performance power kit is available though for 2 grand as opposed to 2500 for the dinan... the MPK does not offer as much HP and torque as the dinan at stage 2. and Dinan is also upgradable to stage 3 which needs an intercooler upgrade to work....which can bring your 435 if you have an air intake, m exhaust, ltd slip diff offered by bmw performance parts up to around 400 hp and around 415 lb/torque

Dinan can't yet "communicate" with any F series N55. Stage 2 software for E series N55 produces 355hp/400tq for $2000 according to their site, plus install at a authorized dealer.

The PPK really isn't that far off. In fact, Dinan dyno'd a E90 N55 with the old PPK and came up with 336/377. Not bad for a product BMW claims as 320/320 (old PPK). The engine is a torque monster.

You must have hit your 1200 mile break-in period by now. Love to hear your experiences with the extra grunt offered with PPK.

Wow, thanks for the info... U did a much better job explaining it than me... Tom I am having the M performance Exhaust installed... There will be a break in period... I am at 2100 miles so I've been punchin it.... Have some interesting stories about guys in 3s coming up to me constantly saying wow. Next I am opting with the MPK to be installed shortly with the air intake upgrade by BMW and LSD mod by BMW.... I wish I could do it all at once....but it's a lot of cheddar and you wouldn't believe what I owe for my lease return of my 3.....over 6k ugh

Got to love how BMW's are known for that.
I actually think they overbuild their engines and then detune them.

So we as consumers can spend $2k more on a "power kit" to experience what the 435 should have been from factory. They absolutely detune them. Aftermarket piggybacks going for $500 are safetly adding ridiculous amounts of power without requiring any other modifications.

Apparently Steve Dinan stopped by a dealership in San Diego very recently and said the software tune for the 435 is about a month out. I heard this from someone who spoke with the lead tech at the dealership. Take it for what it's worth.

Around summer time we should see more aftermarket parts for the 4 series

I expect alot being the coupe version of their most popular car.
