M340i...) - BMW OEM part number 13518631642 or a Dorch / XDIHPFP.
The power gain across the complete power band is pretty impressive and the performance numbers are simply incredible. At the moment we offer
95/102 and E30 variants, 91/95 and 93/98 variants are in beta testing. The В58 is a high compression engine, low quality fuel and high boost can cause issues and we always want to offer
100% safe and reliable maps, the ST2 maps already nearly maxes out those fuels, thats why we need some more time on testing the low quality fuels at high boost ST2+HPFP maps and then decide if results are aood enouah for a maps already nearly maxes out those fuels, thats why we need some more time on testing the low quality fuels at high boost ST2+HPFP maps and then decide if results are good enough for a release.
We also updated all our B58 GEN1 maps to V3.1 with big improvements to the low end and overall drivability.
The top speed limiter is now fully deactivated on all B58 cars (294KPH before) and we applied some changes to the cooling options.
Performance results on B58 GEN1
ST2+HPFP ЕЗО тар from one of our beta testers (M140I XDrive SAT):
1/4 Mile 10.72s @ 128MPH (B58 GEN1 stock turbo world record!)
100-200 KPH in 6.9s
0-100 KPHin3.Gs
0-60 MPH in 2.87s
Dynojet:522HP/743NM

Hey I'm fbo with dorch stage 2 hpfp stock turbo m240i. Running the latest MHD stage 2+ e40 map is impressive. I contacted Wedge to see he could produce a stronger map. I'm looking for 500whp since some have achieved it. He didn't seem to know if his map would produce more power. So, I told him I'll reach out to the community to see if anyone has gone from MHDs strongest map to his custom map for feedback. It would be nice to know approximate whp from MHD OTS. Anyone have feedback. I know scenarios will vary but any help is appreciated. Even if you went with other custom tuners. I don't mind going with another tuner as well.

If you have a stock turbo, there is no point in a custom map. MHD 2+ is enough if you have the right fuel. Only if you change the turbine and add methanol, then you need a custom map.

Not bad.
I guess it's pointless to pay $500-$600 for 10hp-20hp. Not upgrading turbos right now so I'll have to be satisfied with what I have. A safe, reliable and good tune.

Also, Fabian with Pureboost told me he could produce a map 15hp-40hp more than his stage2+ e40 he made for MHD. Nothings a guarantee though. Turbo probably won't last long like that. So, I think I'll stick with what I have.
