It just depends on what you're using it for, all terrains have a much quieter ride than the mud terrains, but I don't think there is any sort of notable mileage difference.

Would an exhaust help with gas mileage?

Ive been trying to do but I haven't had the time and to be honest I'm not very mechanicly inclined but I will do my best tommorow to get it right.

Ok I tried to do the test and the truck wouldn't start so I have to figure that out then I will do the self test.

The engine not being warm wont affect the results?

two of the codes you will get will tell you the engine and trans are not in normal operating temp, but you will still get everything else.

ok so i just pulled my first set of codes, this was the KOEO i got, 11 62 233 336 33

i dont know if i counted wrong so let me know if those don't make sense, i did do the test twice tho. is there a place where i can put the codes in so i know what they mean?
