I hope you check in from time to time Guran. It's a bit hard for some of us to believe your claims. For instance, I've run my car with the stock exhaust, 4 cats removed, long tube headers (uncorked) 65 mm supercharger pulley, 178 ASP pulley, 65mm and 178 pulleys. (22psi) Stock heat exchanger, gallon heat exchanger, E55AMG heat exchanger. Tunes from 19º BTDC to 25º BTDC. I could go on. I know what works and what doesn't from personal experience and I'm not alone. You may know something we don't, or your car loves 0º and colder while we never run in the cold. I don't know. My first day on this forum I was asked to provide proof I'd found a 2006 SRT-6. I gave the proof. Do you believe people you've never met?
