@Gemini estimated boost, hp, nm on the stage 2? optimized for downpipe and big ic?

Stage 2 here is basically the DPF-off aggressive map with reworked injection, rail pressure and boost limiters — the listing gives you the headline number of 286PS / 210kW, but it doesn't publish target boost or a torque figure, so I can't quote you a real Nm/boost value from this file. Anything I'd throw out would be a guess.

For reference on the platform (general, not from this file): a healthy 335d M57D30 on a Stage 2 map typically lands around 620–680Nm and peak boost in the ~1.8–2.1 bar absolute region on the stock VNT setup, but that varies a lot with fuel, health of the turbo and how conservative the tuner kept the smoke/EGT limits.

On your specific questions:

• This is a generic Stage 2 file, not custom-built for a downpipe + larger intercooler. It'll run with a downpipe fine (DPF logic is already off), but it won't be optimized to exploit the extra flow/cooling.
• To actually take advantage of a bigger IC and free-flowing exhaust you'd want a custom read/write with logging, not an off-the-shelf map.

If you want, tell me your exact setup — full ECU read type (full/partial), current HW/SW, turbo (stock VNT or hybrid), fuel and mods list — and I can point you at what limiters would need attention.

@Gemini @Bin you know what this is actually very clever with the AI integration, cheers mate. Do you also do file service with my ista live data logs?

Cheers mate, glad it's useful.

On the logging side — ISTA live data logs aren't really the ideal source for tuning work. ISTA gives you diagnostic-oriented values and fairly coarse sample rates, so for proper file work you want faster, tuner-focused logging (rail pressure actual vs. requested, boost actual vs. requested, IQ/injection quantity, MAF, rail pressure regulator duty, EGT if available). Tools like INPA/ediabas logging or a dedicated logger pull those channels much better on the EDC16.

That said, ISTA logs aren't useless — they're fine for a first sanity check on boost tracking and coolant/intake temps.

To be clear on what I can actually do here: I can help you read the logs, spot limiter/overboost/smoke-limit behaviour and suggest what to touch in the map. Whether an actual paid file-modification service is offered is an admin/seller matter — that's Bin's side, not something I can confirm.

If you want to start, post:

• Your full ECU read (full/partial) + current HW/SW
• Turbo setup (stock VNT or hybrid) and current mods
• A log covering a full-throttle 3rd/4th gear pull — boost req vs actual, rail req vs actual, IQ, and intake/EGT temps

With that I can tell you whether the limiters are what's holding you back before touching anything.
