Considering this for my 6AT, seems pretty legit from what i have already read. Just wanted everyones opinions/experience with it. Looking at going stage 2.

There's quite a few threads on xhp. I'm running the stage 3 and it is the best mod I've done to my car yet

Is stage 3 harsh to daily drive? Is it good to cruise around with and still play hard

As per others' experience and comments on other threads, in Drive it's a non issue.

Reading through quite a few of these threads, seems that Stage 3 is the consensus over Stage 1/2.

Just updated my stage 3 tune and noticed they now have a stage 4 for strictly track use. Doesn't look much different than stage 3

I did xHP stage 2 to my otherwise unmodified 335i 6 spd auto.

Bit underwhelming. It's difficult to say whether the changes have become quicker (or in fact slower I think sometimes) compared to stock. I used to think it was better than stock in M/S mode, but recently I'm not so sure. When I get enough time I might uninstall it and see.

It definitely doesn't drop down gears quickly enough (say from 6th to 4th) for overtaking.

Nothing to do with not having a modified engine.

The gear change indicator in all modes is nice.

Like every performance mod over time i think you get used to it. With MHD when i first flashed i was like WOW!....now im like meh.....probably just means i need to flash Stage 2...haha.

I got stage 2 because I don't really crank on it.
I still know it's a big difference from stock. I entertained the thought of upping to stage 3 but nah. Maybe if I feel like ditching $100 for the experiment.
XHP and MHD is a great combo.


Honestly you should just do 3 and be done with it, believe the hype.

I successfully installed the backup file and the flash module, but upon trying to flash a OTS map I get the error: TCU not connected.....

Not sure what to make of this as the two prior installations went smoothly, am I missing something here?

turn the car off and on again, check all connections, make sure the battery is still charged and try again

[BM3Rrrr]

Yeah it worked finally......

I’m seriously considering doing the XHP flash. My performance shop mentioned it the other day after getting my AA re-tune after header install.

I would prob do the Stage3, but there is a stage4 now? I’m guesding that’s for track use. My car is not a DD so stage 3 would prob suffice.

What’s some of your impressions when this is combined with other increased HP mods? Thanks

yes it's good. do stage 3.

read the description of stage 4 - it's not what you want. it's specifically not recommended for road use.

Thanks, although all the research I’ve done I’m not sure it’s available for the N52. I haven’t seen any flashes done on the N52 engine. Can anyone confirm this? Thanks

*nothing for 328i/328xi on the XHP site.

To check compatibility download the xhp app and connect it to the car. If your car can be tuned it'll show that it connected to the car

Sorry, xHP not available for your car. The 328i N52 is one of the rare models, that didn't get delivered with the ZF automatic, but a model from GM. xHP does only support ZF automatics!
