F80 M3 S55 - stage 2 build thread

I tuned my wifes X1 20d (190hp version) and its a completely different car now. 240hp and 480nm makes it feel like a proper SUV instead of an underpowered crossover. Highway overta...

B47 is better in every way. The N47 has the infamous timing chain issue (chain is at the back of the engine, replacement requires engine removal, costs 3000+ EUR). The B47 moved th...

The 118d is a great commuter car and stage 1 makes it even better. The N47/B47 engine goes from 150hp to about 190-200hp with a remap. More importantly, the torque increase (from 3...

Yes, diesel tunes can improve fuel economy. My 530d went from 6.5L/100km to about 6.0L/100km on highway after stage 1. The reason is the engine makes more torque at lower RPM, so y...

Great results! I got very similar numbers on my 320d. The B47 is one of the best engines for chiptuning because BMW left so much headroom in the stock tune. The torque increase is ...

Good comprehensive guide. One thing to add - if you do a DPF delete, also consider doing an EGR delete at the same time. Without the DPF, the EGR valve will clog up faster because ...

The 6 Series GT is massively underrated. I have the 630d with the B57 engine — 286hp stock and with a stage 1 remap it pushes 340hp with over 700Nm torque. The car weighs 1.9 tonne...

For diesel guys - if you're doing a DPF delete, make sure your tuner removes the DPF regeneration cycle from the ECU map. Otherwise you'll get constant regen attempts that dump fue...

Had the EGR cleaned on my E60 530d at 160k km. The intake manifold was absolutely disgusting - completely caked with carbon. The mechanic said it was restricting airflow by about 3...

M3 diff is the cheapest option and works well. Just make sure you get the right ratio for your gearbox. 3.62 is good for track, 3.46 is better for street.

Make sure your network adapter is set to the correct IP range. For ENET, you need 169.254.x.x subnet. Also try disabling all other network adapters (WiFi, etc).

Black paint is the hardest to maintain but looks the best when properly corrected and coated. Nice work on the paint correction!
