I have a 2007 Chevy Dually Diesel w/ Allison transmission that I tow a 37 foot TT with. I generally get 10 to 11 mpg towing on relative flat roads. Worse in the hills. My diesel mechanic has recommended that I add an Air Dog 150 Lift Pump to significantly increase my mpg as a beginning fix. Cost will be around $900 installed. He also recommends adding a EFI Live Duramax Tuner at a later date. Cost for this will be in the same range. When all is complete, he says I should get around 20+ mpg while towing.
Has anybody else completed these upgrades? If you have, what results are you getting and would you recommend this upgrade?
He is full of "Barbra Streisand" !!!!!!!!!!
Ask him to put it in writing with a money back grantee.
INCREDIBLE!
