    I have a 07 5.3 Silverado and am looking into getting a programmer mostly for gas mileage. I have read up a bit on them and am wondering if theres a programmer that can control the points at which my engine goes into v4. I think it would be great to go into V4 while idling or to better control the v8 v4 action while driving around. Any one have any ideas?
