what should be the temp range for a stage 2 EJ20 Idle ? Hwy speed 60-70 mph Currently I noticed when engine cold it gets up to 900F then drops back to 800F. running 50-60mph = 1200F (approx) Probe is on the Driver side manifold EGT/BST gauge
If it goes much over 1500F then worry. At about 1600F the aluminium in the engine starts to soften. Thats something to worry about.
