Engine Performance
I have a 2005 GulfStream Endura built on a 2004 Chevy Kodiak chassis, powered by a Vortec TM 8.1 litre V8 gas engine. I would like to know is there any way to increase the performance and give me bett...

The best you will do is slight. However, keep things CLEAN. Oil, air filter, good plugs - will do you very well. Tire pressures correct will also do you well. I prefer to run a bit of Marvel Mystery Oil in my fuel to clean/lube the upper cylinders valves. Also remove dead weight (keep things physically clean and remove items unused).
