Just fitted a boost gauge and for any queries it hits a bar and then settles down to 0.8 which is the same boost as my mates supra 3.0 twin turbo manual is running just a shame it doesnt have the power as that haha
my boost gauge runs 0,8 bar over, 0,5 bar constant !!! are you sure with the numbers or have you changed the arm setting ? what brand is your gauge maybe it is an optimistic one. ihi vf 32 is suppossed to deliver 0,8 max (factory setting)
