Just got the call from Arringtons and my 300SRT is NOW retuned and redyno'd. The final numbers are 662HP to the rear wheels & 582Lbs of torque running 13Lbs of boost. I wonder what the horsepower at the engine would be putting this much to the wheels. To Late today to go up and get it back and tomorrow, we have to babysit the grandkids; hopefully it won't be all day so Tee and can go pick up my 300SRT "CHEETA"! Man, I am excited! The tune, new pulley, new belt and dyno pulls cost over $1000. Yikes!
