ive had my twin turbo for about 2 months now, its been absolutely perfect,
will heat up in next to no time, hot air will come out and thats it
now then last week i headed off out for a burn and i got to a lenghty bit of road and after tha car had already warmed up (so needle is halfway) i dropped it into 4th gear and planted my foot, i then noticed as soon as my foot was down boost gauge went round, then the temp guage went right down, literally like quater of the way down. But i hadnt actually moved much more further for it to possibly cool itself down and not that quickly.
It cooled itself down as quickly as it boosted up, so i backed off and as soon as i back off its fine again and returns to halfway.
ive done the basics, checked water level, airlocks etc and theyre prefect, the heater never goes cold when this happens, always stays nice and warm. ive even checked the plug connections for a dodgy connection and thats fine.
now is this just a coincidence with the weather and that it just so cold out there its cooling it down, but surely it cant cool it down the quickly??
im really stuck on this, and am more worried if something major is wrong with it???
any help is much much much much appreciated cheers guys
