I’m curious to know what your 0-100 is. I also definitely plan to do ecu unlock, tune, and upgraded turbo down the line as well.

With a piggyback you can easily go over 500hp, so Bluespark's figures of 510-520 may be correct. ( see the chart below of mine 45e with a piggyback).
However, there are two important points to be careful of...

This one does NOT have user configurable maps; only the 1. So their description is wrong and also don't order it with the bluetooth as that's a waste since it is not adjustable.

91 or 93 octane is fine as the unit will adjust on the fly to the timing/cam position and takes the mass air sensor into account.

Turbo lag is non-existent with this module and more boost is easily felt. No question that this is the absolute cheapest power add-on for ANY car I've seen. Delivery was only like 8 days using the slowest method. Install is ridiculously easy, BUT I fit my unit by the air box neatly tucked away and hid the wires almost completely. My car still has lots of warranty. I've never had issues with BMW service for 25 years. One time in a new Z4, one of my speakers blew so I brought it in. They asked what happened and I told them I was listening REALLY loud and the speaker blew. They replaced it free since I told them it should be able to handle any volume lol.

Message here if you need any help.

Coming from the VW/Audi scene, this is disappointing news for sure. Correct me if I've misread anything in this thread, but it would appear there are literally zero 'off-the-shelf' stage one, two, etc. software performance mapping options (only these piggyback systems that seem to offer a more sophisfacted version of wastegate tweaking the turbo). And given the engine's timeframe in production, it does feel unlikely that a company is going to invest in a proper mapping software that doesn't rely on the engine adjusting on the fly. Very sad news as it certainly feels as if this car has a lot of untapped potential even with a very moddest (safe) stage one/two software upgrade.

So what are the catted downpipe options for the X5 45e? I have the 2022 X5 45e with no OPF. I'm not seeing many options that specifically state the 45e.

I understand the exhaust is a 2 pipe on the non-hybrid X5. So is there 2 downpipes on the non-hybrid, or where is the split point? What are our exhaust options? Or are they basically just custom?

I've done the burgertuning billet intake & intake hose, removed the resonator, and BlueSpark on C. It is very impressive. Have a charge pipe on the way and want to do the downpipe and exhaust.

Yesterday, the 45e project was completed.
In the meantime, we installed a DO88 intercooler, so high IAT is no longer an issue.
The final version includes 4 maps (via MHD Mapswitch), each with different performance levels.
The original plan was to have Stage 0, Stage 1, Stage 2, and Stage 3, but the Mapswitch function doesn’t seem to store all tables separately on the hybrid, so Stage 0 ended up being a bit stronger (~500BHP/700Nm) compared to stock (~410BHP/580Nm).

Hybrid control is a bit tricky, as it allows you to configure how much assistance the electric motor provides in each mode.
By default, this is limited to 150Nm, which we unlocked. However, the transmission still limits the system, so up to around 4200rpm, Stage 2 and Stage 3 feel equally strong — even though the combustion engine produces more power in Stage 3. If xHP releases a version for the hybrid in the future, this may change.

Looking back, I think the upgraded turbo wasn’t really necessary.
The power of Stage 2 would have been more than enough... 100–200 km/h is already around 8.8–9.0 seconds, which is quicker than most stock X5Ms.

The calibration optimized for the bigger turbo only shows its advantage in the higher RPM range, not in everyday driving.
With this setup, 100–200 km/h stays consistently in the 8.1–8.2 second range. It's optimized for RON100 Pump fuel (12degrees ignition), I guess with ethanol a 7.XXs would be possible.
It also performs very well at higher speeds — the sub-8 second 200–250 km/h time is on par with a stock M2/M3.

Would you mind posting a link, or DM me, of the specific D088 intercooler you installed on the 45e?

I did mine. DME tune, down pipe and custom dual valve exhaust. Exhaust is following DME logic.
Result dynoed is 556hp /780nm
Just keep in mind depending on your local bimmer dealer you will likely lose warranty. But it's made my car into a beast and I have had zero issues. My tune is completely within engine tolerance. It's a stage 1, stage 2 requires a different air filter plus gasoline pump. That will add around 55-60hp more.

Hi. Several years have passed. How is your car? Any issues with the drivetrain?

Did the d088 intercooler come with a phenolic spacer?

I have a Wagner intercooler on my 540i and noticed on the the last drag racing event, it heat soaked badly while queuing between runs. I have a spacer to put on when i get time and can also transfer it onto our X5 if i ever de-mod my 540i

Zero issues so far. Knock on wood.
