The other day i had been "playing" under the bonnet also had to reset home possition of the sunroof so included taking the battery off,
The wierd part of this was when i was out driving about an hour after... i did about 20 miles then as the roads cleared "pushed on a little " the car felt great, I checked the boost gauge and... it normaly spikes at about 24 psi then holds 22 through to the limit,
With the AFR gauge reading between 11.7 and 12.0 under full boost ,
This time i was seeing 28 psi dropping to 25 but with the same AFR readings.
The weather was very misty and showing 4.5 degree on the gauge .
Is this down the the colder dense air? or something down to the fact i reset the ECU?
