Well this morning I started the car and quickly checked iat with nanocom it was 15 degrees centigrade, so in good working order.

Guess what, no problem with the gearbox on departure, no need to apply full throttle to take off.

Will keep a close eye on this for the coming days for sure.
 
Hi again guys,

I’m in the alps on the Italian border. Took the highway to get here. I’m running bigger tires and this also heavier tires. It takes a while to het up to speed but managed to drive 110km/h for the most part.

But now I left the highway in search for a place to sleep and the car felt very sluggish and had a hard time reaching speeds max 50-60km/h if I push harder I get a whole lot of smoke. I also noticed more black smoke than usual, could it be that the turbo is on its way out? I had to add oil as well about 0,5l /1000km

Why do people always try to blame the turbo? they are very reliable on the M51 engine. Split or delaminated hose, MAP or MAF sensor faulty are just 2 of the other possibilities.

🤣 I quess that’s how it feels. But all hoses are new silicon hoses and it’s a map sensor for mine which is also new. I could blow through the small hose from sensor to manifold to see if it’s better.

New parts do not always work these days, needs diagnostics to check the MAP output.
 
Intercooler also bigger one. What would be a good reference value for the map sensor as a reference?
About 1 bar above atmospheric pressure maximum with the engine under load. On my diagnostics, atmospheric pressure is shown as well as boost pressure, at idle the two figures will be much the same.
