The BD, PW, etc, injectors are Bosch injectors, from I believe an industrial or marine app. About two months ago, Bosch doubled the price of them, making them basically too expensive for the gain. Lots of guys tow with them, and have had no problems with them. Many noticed a gain in MPGs as well. I have a set of EDMs, and am quite happy with them, though I have yet to do any towing with them. I think I am one of the first to put them in a non intercooled pickup.
Welcome to the TDR. FIrst thing you need to do is make yourself a signature- go to the user control panel, and click on edit profile. THat way, we can just look at your sig, and not have to ask what year truck you have, and if it is a stick or auto, 3. 54/ 4. 10, etc.
