Custom engine build tune suggestions.

My x48 blew up and spread itself throughout my engine back in march, basically determined i had to rebuild the engine, so decided why not just go all out? So I did, engine is still in the works, mrx ported head, v2 cams, sleeved closed deck block from sp63, billet crank from callies, etc.

Now I'm just looking into tuning since the engine should ship relatively soon. Was originally looking to get a syvecs and get it tuned at a local tuning shop, but that’s been pushed slightly out of budget with some other things that still need to happen, so I'm looking for different options.

Are there any recommendations for setups like this? I’ve been looking into a cobb access port with a custom tune from dizzy tuning or tuneplus, both seem promising, however i’m in the netherlands, so it will have to be tuned remotely, and I'm currently most concerned about keeping the engine together as it costs more than the car, so I'm interested in what sort of safety features they offer and what is even possible with the stock ecu.

Currently have a s280 ready to go on, aiming for about 350whp, going s290 or g25-550 maybe in a year or 2, haven’t decided yet. Already have 30% larger injectors, still stock hpfp for now, everything else is basically fully upgraded except the gearbox.

If you guys have some recommendations, maybe different tuners which i have missed, different options altogether, or whether i should just save up for the syvecs and deal with a car that doesn’t run for a couple more months, i would love to hear it.

What did you end up doing as far as tuning for this?
It's currently not running yet because of tons of delays waiting for parts, but I've got all the parts now and have bought a motec ecu and am getting it tuned at a local performance shop in the Netherlands quite soon.

Your APK/RDW allows you to run a car on the street with a stand alone ECU??

They do not do an OBD plug-in check there during the APK inspections?

From what i understand and what my tuner tells me, there are certain emissions tests that will not be possible, however there is the option to do a different emission test for like 15 euro more, which you can pass with a stand alone ECU. My tuner also does the APK inspections, so i'm not too worried about it.
