Overboost On Cold Cold Night?

Hey guys, last night I was driving home about 8pm air was quite cold. I took off from a set of lights with a bit of a boot full nothing I havent done before with traction on.. Now it began to take off then traction made a big sound and the light lit (it didnt flicker like it usually does)..so wheels spun a liitle..soon as that loud thump hit I had no power and I quickly looked at the dash to see the revs hitting 6000RPM, although it did not sound or feel like it was hitting 6000RPM..

My question is could this have happened due to overboost maybe because of the cold air that night?

I plugged my sct when I drove the car back home (but kept it off boost just in case, she drove normally) and it threw back a code which was P1000 (something about OBD MAF)?

Can anyone shed some light on this issue? I am yet to drive the car since then but I thought id come here first..

Car is 07 bf mk2 315rwkw, cooler, injectors, full exhaust custom Tune....

Thanks in advance

Ignore that code, p1000 is set when a full drive cycle has not been completed, cant be cleared... Sounds like normal traction control operation too me, if you overboost the engine light comes on and also sets codes, if p1000 is the only code I wouldnt stress

The power loss and thud was probably rev limiter.

When mine overboosted I can't remember the code but it said something along the lines of manifold pressure too high/overboost. And the engine light came on.

I over reved at the drags when it stayed in second and it didn't change up. There was no thud just a silence as it floated in the high revs with no spark.

I have had the odd thud as I gained traction when changing road surfaces sometimes or go over a bump/dip. Not sure how the traction control is supposed to work as mine seems to do nothing :)
