When I first start my truck the map value is usually at zero to 0.1, as it comes up to operating temp the values goes to .7 or. 8. Just wondering if this is normal or not. I occasionally get the 2263 supercharger performance code on my dashdaq as well. I've read that can either be my ebp sensor, or something the latest Ford flash will fix. Any thoughts kn this? Thanks. Oh, the above numbers are all at idle.
