it may not be much but an engine turning 1500 rpm will most certainly use less fuel than an engine turning 3000 rpm just sayin. Again not a big deal it is what it is
no i didn't i normally drive an 06 3500 srw cummins worked out the balls, this is just a runner for me. I had a 13 6speed 3.92 that got about 16 back and forth to work over the mountain was just hoping to see at least that no big deal
Ok thanks guys. This is going to cause havoc On my mpgs I normally can coast for like 2 miles or more but not anymore it looks like. Funny I just talked to a guy I thought was full of **** said his 13 6speed 3.92 got better mpgs than his 15 8speed 3.92 now I guess I can see that happening in my...
I have an ignition orange sport and I also think they fed me the bs gotta be more than 1000 out there. At least I got one with the 3.92 seems like almost everything that's not a diesel up here is 3.21. I will admit I can see getting sick of it though especially since I almost always end up with...
So do I bud I've been building diesels for about 10 years now. I think that's why I'm spoiled I'm used to getting huge gains from custom tuning. I could never justify paying 1100 to get a 30hp max gain that's just me though. I'm used to being able to make 30hp by accident lol
just picked up a 15 sport with 3.92's and 8 speed trans. do these 8 speeds have some sort of trans braking or hill descent control? i noticed when coasting down the mountain if i barely touch the brake it starts down shifting like 2 or 3 gears and now i'm at 3000 rpm instead of 1500 coasting...
Nice, I know livernoise Motorsport is seeing from 77-92hp and 123-127tq on the dyno with exhaust cai 160* t-stat and precision gapped plugs on their 93 octane performance tune. That's pretty dang impressive
Custom tuning for those eb's is wicked none of this 30hp crap just with a few bolt ons to accent the tuning those trucks are getting roughly 90hp just out of a tune
Just FYI the 13- 15 cummins are now able to be tuned via EFI live custom tuning it runs about 900 for an auto-cal preloaded with custom tunes and another 50 bucks for an unlock cable this will also net you about 120-130hp at the wheels
i just picked up a 15 sport on sat and thinking about the vararam i normally would use s&b my concerns are water and other road crap getting in there any thoughts on this
