I have a php Phoenix chip and am going to send it in for a reburn and going to change the tunes I have. I am wanting opinions on the whisper tune and the 140 extreme. I have the 120 race now which I use when not towing and have been seeing pretty good mileage out of. If I get the extreme I will not be hard on the truck all the time but I am wondering if I will see better mileage than the 120 race and also if the shift pattern is different. As for the whisper tune I have read mixed reviews, so just want to know who likes it and who doesn't. New tunes may be stock, 65 tow, 80 dd, 100 race, 140 extreme and whisper. Opinions??
Thanks
