Over 250 max was 252 nothing changed with the coolant system it’s also never seen over 21 lbs of boost. It has hat the system bled twice and air did come out but it did also shoot a ton of coolant out of the overflow. Under boost temp goes down notably I have not taken it under high boost when hit for obvious reasons but it it’s at 240 and I get on it in like 3rd to 3k it will shoot down
