Guys, I'm at a loss currently. I'll give the specs as is and see if anyone has some info that'll help. Ok I have a 2012 model y61. Roughly 50,000ks on the clock. Now i bought this car knowing full well the former issues with it. I've tried to take all steps to avoid the dramas ive had in the past. Too date i have installed a 3' stainless exhaust from redback, which i think is a good product, over the factory setup it really help with the motors performance. Coupled with that i fitted a set of Autron Gauges. EGT/ BOOST and dual battery gauge. Here's where the problem arises. To my knowledge I have the egt probe installed correctly and the gauges don't need any calibration. I was a little surprised to see the temps readings after the gauges were installed. Now i admit I probably have a heavy foot, but the temps were worrying me. Around town it was fine, would rarely reach 300 degrees. On the highway was another matter, over taking or cresting any sort of rise my tepms would reach north of 600, edging towards the 700 mark. Now i'd always heard these motors ran warm, but that was a little ridiculous. Next step was replace the factory intercooler with an upgraded model, I went with a cross country cooler, it was a well recommended product and i'd heard good things, most importantly a reduction in egt's. Problem is, after fitting the unit, I am not seeing a reduction at all. Maybe, and i stress without doing a pre and post dyno check, i'm getting a 30-40 degree reduction. I'm seriously at a loss. I'm trying to protect this motor, but i'm running out of options. Is there anyone out there with a similar setup? Or just general info would help Thanks
