200+ is normal operating temperature when sitting and warmed up. mine drops a bit of power once its hot. ive given up and determined that to be normal. If i had to guess its either old 02 sensors, or less gas being shoved into the engine during warmup because its done warming up.
also, if you cant afford upgrades, leave it stock. that's what i do.
so what year is your car? 02+? do you have the pink injectors?
