If your running too high egt's, like 14-16, way too hot. 400whp at just 20psi with puny 20g turbo and my egt only go up to 13 under load. Plenty of guys making way more power with same egt, just bigger turbo.

The intercooler system is designed to lower the compressed air temperature from the turbo, through the air-to-air intercooler and back into the intake. Cooling the inlet air increases air density and maximizes engine performance. The inlet air temperature also lowers firing pressures and reduces stress on the engine. 10 degree drop in air intake temperature, an engine can increase performance 1%. For example, reducing the air intake temperature 200 degrees would equal (200 * 1%) a 20% gain in performance. In addition, lowering exhaust temperatures can increase engine efficiency, extend life and reduce engine operating temperatures. Higher air intake temperatures reduce horsepower, engine efficiency, raises exhaust temperatures, and overall engine operating temperature.

My egt sensor is connected to manifold off of #1 cylinder. Don't have bad set-up if running 14-16 egt under load, but if you have cooler inlet temp. you will have more power becuase lower egt.
Last 2 sentences from quote prove inlet air temp directly relates to egt temps. This is basic thermal dynamics. Another reason I believe my egt lower then others is because shorter duration and lift of my exhaust cam. All this is healthy talk about egt's, timing, a/f ratio, etc. You can have perfect air/fuel curve tuned correctly and have high egt or low egt. Every engine different.
