Last winter did it a couple times, and today just hit 1.5 bar. Only seems to do it when it's really cold.

 

Cold temps makes the air denser, denser air makes it easier for the engine to make more power. So you may show more boost in colder temps.

 

So it's a false reading?

 

I'd check your waste gates. My car boosts 1.3 bar no matter if its 90 or 30 degrees outside. I do seem to hit 1.3 bar a little lower in the rpm range with colder temps which makes sense due to the denser air.

 

generally speaking, on an electronically controlled system, cold air shouldn't change the boost pressure much...more power yes... but more boost made,no

 

.1 bar more... yes under colder conditions...

 

what do you normally boost at?
Normally yes you can make a couple of extra lbs of boost when its very cold but whats your reference, thats a hell of a spike if its stockish, becarefull.

 

^ my boost levels stay the same also ( 1.3 ) even in summer heat but cooler and most particularly fog (?!) the car just seems to "breathe" better and it sure feels a bit "quicker".

but definitely agree, waste gates improperly adjusted can/will cause "boost creep". i messed with mine for a cpl months until i got it sorted. i was getting 1.5 spikes and my car isn't set for that.

+1 on 993gt. feeling like more "power" but shouldn't boost higher. agree.

 

Something is wrong
stop by I will find it... your N75 is probably leaking at the connections.. Wgs not opening up.... or even a tune etc...

 

Normal is 1.0 and 30% of the time it's 1.1.

 

I can't. I will come home with injectors and turbos.

 

I literally LOLd.

 

 

I'd stop driving the car hard, agree 100% with Markski, issue controlling boost down, 1bar vs 1.5 is huge...

 

I know i have a leak somewhere. Never really savvy with checking. Been wanting turbos from markski for a while and get it all sorted out. The budget always seems to go elsewhere.. :-/
