Title: Long time no speak.....boost advice needed
Post by: NEWEY on November 20, 2010, 04:39:11 pm
Hi guys long time no speak. Hope everyones ok.

I've come across a little problem on the car and wonder if you could help. On my boost gauge when on tickover the car used to sit on 20hg or slightly under. I noticed the other day that it's started sitting on 19/18 hg. Anyone got any ideas on why this is? The car is running well and still pulls very strong.

For anyone that doesnt know the spec of the car it's Milltek turbo back stage 2 sportec map and forge dv

Cheers

Atmospheric changes? If the barometric pressure changes this will have an effect on any vac/boost readings.

There has been a big change in barometric pressure over the last few days over most if the uk.

That's useful to know, PDT  :drinking:

Obvious when you think about it but easy to miss the reason.

I input barometric pressure, outside temps, humidity etc.... About 15 times a day into the dyno, i can tell if its started raining without even looking outside the dyno cell.

Yes, but a saddo and a geek that gets to tune and map engines, play with and test tuning parts on the dyno and drive various high powered cars for 8hours a day and get paid for it  :booty:
