Re: 2008/2009 owners..... Premium fuel question??
Vegas....... Im well aware of the Placebo effect, have owned alot of modded cars/bikes and dont usually count horsepower till I see it on a dyno or get results at the track. I too laugh at posts on forums about the guy who installs a K/N filter and can feel a "HUGE" boost in horsepower....
Im not talking a night/day difference but there is a noticeably better response in the lower RPM along with the trans acting better.
I owned an 06 prior to this 08 and running premium did nothing in that truck so I can see how you may make the "placebo" statement based on the fact that you own a 2005..... there have been past threads here regarding the use of premium in the 2008/2009's due to knock issues, rough idle, low RPM gear hunting and clunking etc....
