Haha I was just about to start the exact same thread!
Since I installed my kill switch, I did not see the improvement in my mpgs I thought I would have.
I cant figure out the sweet spot for optimal fuel economy. I can't really p&g in town because of traffic and stop lights. I dont know if its because of high winds but short highway trips seem to hurt my Mpgs and p&G does yield better results.
The sweet spot for my trucks for full economy is 52km/h in fifth gear with 20hg/in of Vacuum, gives me about 5.5l/100km depending on terrain.
I use my kill switch comming to a red light (in 5th gear) or coasting down a hill but other than that p&g eo does not improve my fuel economy and I cant figure why, heck I got better results EIC... Wtf?
I think I do not live in an area promoting Eoc or p&G due to terrain, somewhat dense traffic and to much stop lights.
