New computers

Well, 10% would be noticeable...

Most accurate tests by the most skilled mechanics show not much difference between carb & EFI on either power and mileage. However, carbs go out of tune much more often. Therefore, most folks with carbs are driving them around in an out-of-tune state. That's why EFI is much better overall. With a computer controlling the tune (and able to change as parts wear) you really don't need to do anything except change plugs every 10 years or so... ;)

UNLESS you tinker and fuck with it a LOT, Like ME, it's a toy above all.....

looks like my old tired (allmost tired as ME) 318 powered Dodge 3/4 ton work van needs learn DPFI also....but I understand the new ones did only slightly better at 13-14 mpg...this thing gets 10 mostly and 12 on a good day downhill with a tailwind....

damn brick....all 4400 lbs of it....and that's dead empty filled with helium....
