OK I dont have a supra so if this needs to be moved I will understand, I have a 240sx low compression pistons, forged rods and just installed my EGT tonight. At 13 psi with the wideband 02 sensor hooked up I was reading 12.2 on the wideband, and just rolling on in second and then to third my EGt climbed to 900. I heard that 900 is too high so I let off. The probe is about 2" from the head in the manifold. Is 900 to high? Even for forged pistons? Also I have been running my car for about 4 weeks at this boost before I got the EGT so it has been running this hot all olong, I just didnt know until now. Any ideas?
