Right guys iv got 2 niggling issues on my car Since turning the car back to standard.

Iv had toyo's put on front and rear 225/50/15 and 205/50/15 on front.

The car has only done a 1000 miles of driving this year as now its a second car.

Everytime I seems to hit full boost you seem to get sideways and its just abit annoying when you pull out to over take.I have read on here that people run diffrent tyre pressures now can anybody reccomend a tyre pressures for the t1r, I was running standard was looking through the search the other day and somebody say 34 and 38 in the back but this doesnt feel right either please help.

Second one is MBC to turn the boost down on a grainger valve is it screw out or screw in

?

Cheers Daz
