Message	The tune required for DW injectors is all over the place. What you have posted is extremely common for DW injectors running a standard tune. Some DW injectors are not tune-able, others can be tuned but require a lot more work in the fuel maps and funky K and L values. From what you have posted, it sounds like yours will be tune-able. If you buy higher quality parts you have less headaches. Do not worry about what the values are with those injectors, you probably need to add more K, but you always have to adjust the fuel maps with those injectors. The fuel has also changed a lot in the past few years, more ethanol is being used causing leaning mixtures.
