Default Drop in Boost Pressure

I usually hold 15 - 16 pounds of boost. On my way home just now I got on it a little bit and it was holding between 13 - 14. I have only put 93 gas in my car since I have had it but my last fill up I realized I accidentally put in 92. You think the 92 gas is the culprit or a coincidence?

was it really cold down south today? boost drops in really cold temps, i live in ny and have a friend that lives in miami and it was 28 down there today

my guess is it was really cold down there and you probably never see temperatures like that, thats why this seems so odd to you

when the temperature drops air becomes more dense. So basically the car needs less boost to achieve the same output. Perfectly normal. I usually see 17.5 but with the colder temps I usually run between 12-15.

Your fortunate enough to get 93 where you live, here in NM all the stations have 91. There is a place I can get 101 but it $7.00+ a gal. This car is very gas sensitive, got some bad gas once and was casuing a miss fire.
