Attention: TDR Forum Junkies 
Had my first long tow with the Schwitzer S-300 custom turbo. Truck is a 2004. 5 6 speed, other mods, Edge juce and attitude, MBRP exhaust, 3 piece ATS exhaust manifold, A-FE intake. This truck has always towed at least 19,000# every time it is running, it has traveled about 300miles of the 100,000 on it without the load. The exhaust temp has always been high even before the mods were added. (I had seen 1400 bone stock) The hard towing temps has dropped at least 200 Degrees, the spool up is a bit slower than stock trubo, but I just modified my driving style a bit and it works very well. , Pulling performance has improved markedly for the better, This is now a completly diffrent towing vehicle. The S-300 has been a "Best Buy" for me.
