Hi. We have a optimax 200 SST with 3 hours from new. After 3 min running it holds Bach and throttle is reduced. Scan says port bank EGT too high 68deg. Starboard bank 55deg. Throttle position sender reads 92%. Throttle flap is full open. Also reads water pressure at 41psi ?. My thinking is actual throttle is fully open but ecu thinks only 92% open. So running lean at top end ??. What I don't understand is why water pressure needs to be 41psi ??. Do we need to remove the stats in head . or should I look for blockage. All seams fine with water flow. And compressor is not hot.
Any help or ideas on please??
Thanks. Carl
