Wellllllll... i installed a lex and 550's. the car feels insane under boost with my Holset turbo. Im pretty sure i'm running a little lean. would that create higher coolant temps?

Engine temperatures will increase with higher EGT's (Exhaust gas temps) flowing.

Leaner = hotter.

Heat will transfer from the engine to the water.
Poor radiator function will not be able to maintain water temps very well.

It would behoove you to purchase a WB, so you can tune around "lean" conditions.
And possibly check your cooling system for efficiency.

What the fuck are you doing messing with AFM's, Injectors, and bigger turbo's without WBO2?

Jon, you seem to know him, so go slap him upside the head
