I E the pushrod nor valves move either...when the ECM sences a change in the load (going up a hill), or more gas (pedal position chages outside the limits) it switches back to 8cyl. mode... it does this in meer milliseconds and cant not be detected, other then the exhaust tone....as a matter of fact those DOD cylinders receive less ware do to this function....
Scoti,
welcome to the club.....you know we'll require a thread with pics  |
I talked with Howell feul injection as well as street and performance and both said it is not worth doing. So for my 05 5.3L who would you recomend getting a harness from so this function stays active? I am trying to get the best MPG I can out of this truck. It has 3.27RP with the 4L60E but the whole cylinder dropping has me at a loss at this point. Any imput would be great.
Also I missed it last time but nice job on slicing the rocker to fit the door/fender profile. Most poeple don't take the time to do this and it really pays off in the end.
