'Tis was rainy Christmas Day. Got to data log my car and noticed the knock counts were "much" less compared to dry condition. My mods are 1G bpu+.
I suppose that when it rains, it's safe to raise the boost higher. Some advantage of turbo cars. Basically, moist air is cooling the stock sidemounts better. Can imagine on fmic cars.
Turn up the wick :cool:
 
I really would recomend against turning up the boost in cold weather seeing as that not only does it cool the sidemount better(which is good) but it also makes the air charge more dense. Which, in turn will ultimatly cause a lean running condition.
 
it will only cause a lean condition if your fuel system is at its last lims... if your on a 14b, and you have 1000cc injectors with a walbro 255 hp, going from 14 to 16 psi wont cause lean conditions, but if your on the stock fuel system, this is good advice, be aware that you will run out of fuel easily, and a lean engine is a hot engine.... VERY HOT... causes a lot of problems...
