wanna make a bet if I asked this same question over on the PSD forums I would get people swearing up and down they get better MPG, more HP, 30 second warm up ..... etc...

Sucks how information gets repeated over and over regardless if it true or not. One guy believed the hype and swore by it, so now its just common knowledge.


But seriously Dieselsite has very high quality products! I recently purchased a few products from them and I am extremely impressed! Very professional business to boot.

I installed one last march I couldn't tell much if any improvement in performance. The biggest difference was the heater and less black smoke when I really layed in it. Although even with out a manuel gauge I think my old stat was opening to soon even for a 195. Reason being my heater wasn't the greatest and my oil temp would never get over 160 unless I was running 80+ down interstate for awhile and then might hit 165. I do think I gained a tenth or two in mileage but could have been a fluck.

I would like to make a comment here. I do believe that running ur truck at a higher temp will increase ur fuel economy. For a diesel Im not sure for gas yes it makes a difference. I have done alot of fuel economy research and to get better fuel economy U want to run a hotter engine and suck warm air into the intake (not turbos). It creates a hotter combustion which helps burn the fuel more completely. So if it dies anything itll help ur fuel economy. hp and that other stuff I dont think so.

I work for the railroad on 4500 hp engines and we run our locos hot for that reason. The fuel is also warmed to atomize the fuel better mpg.

I hope that helps i say go for it.
