I decided to come back here and add the latest information that renders all prior information null and void. I'll start with some background. I've had problems with my tunes. A "normal works for everyone else" tune has been way off on my car. My IAT's have been over what the average owner sees. Water meth has done NOTHING to help my IAT's. So I start messing with my heat exchangers. I pulled the supercooler and went back to the stock heat exchanger with a remote reservoir. I pumped out water without reaching boiling temperatures. I figured it must have boiled somewhere in the loop. Next event I bumped up against the supercharger over temp. So I pulled the stock heat exchanger and put in an E55 AMG heat exchanger. Another event and I'm pushing water out the reservoir. WTF! No overtemp, 180º IAT's. Then I started thinking about my intercooler leak and ....... well duh. The boost is pressurizing the I/C circuit, pumping water out, interfering with the cooling, making me chase my tail and waste time. Now my local tuner that doesn't tune Crossfires tells me a leak changes a tune. Another piece falls in place. It's likely the reason injecting water/meth hasn't lowered my IAT's. I never suspected the leak would cause these issues. I figured, a little water won't hurt anything, if you can spray water for cooling a little leak won't cause any real problems. A new intercooler has been ordered. When it's installed and tested I'll come back again with the real results. BTW, the car runs great. Just hot and I've had to retune like crazy and will likely have to retune some more after the leak is eliminated.
