Anyone seen or used these? Promises up to 35 HP and 4 mpg. just wondering if anyone has used one of these and how legit they are. It seems a little to cheap and easy to be legit but who knows I guess
My truck has 3.55 gears and I think I might actually get better fuel mileage if I change it over to 3.73 in the way of thinking that it won't have to work as hard. My AWD Hemi durango w/third row seat and 20" wheels with OS tires gets about 4 mpg better than my ram....what are your thoughts?
I really like the factory 4:10 ratio that came in my '06 2500. If I keep it at 55 I can usually get 14.7-14.8 in summertime, wintertime it drops to 14.3-14.4. It is SOOO hard to keep the right foot out of it though, I rarely get those kind of numbers on consecutive tanks because...well...HEMI...that's why lol

Ive noticed that theres something thats not quite right about how my truck runs. It almost like a miss but its not. I guess the best way to describe it is it kind of sounds like its gurgling sometimes. I changed out the plugs and it disnt change but im wondering if I should have gone with NGK plugs. Everyone was saying just stick with champion copper but alot of the research ive done sounds like I should go with NGK platinum. From what I u derstand the newer hemis come with half copper and half platinum which makes no sense to me.
I've had brand new plugs have a crack in the insulator that caused a misfire. I found out the hard way that if you have a cracked insulator and you touch that particular wire you are a far less resistant path to ground than the cracked plug is. Anyway the easy way to test is to pull one cylinder's plug wires off at a time when if you pull one and don't notice much difference then that is the bad cylinder. Put one plug wire back on and if there is no change then that is the bad wire. If it smooths out then it is the other one. Don't forget to check the coil that fires that plug to make sure it is not the problem.
