Hey Lawrence, I am not familar with LM-1 software, but as Richard says it almost looks like it is running the narrowband reading at first glance. BUT, after a second look it does looks like a wideband reading to me. I see the rich shot at the end, but it looks lean up to that. (12.5x + AFR). In any case, let's not hijack cyazo6's thead. If you want us (as a group) to help, start up a new thread with what you can do to make it fatser within the realms of safety. In any case, if it is my meth tune you are running with meth turned off, that motor WILL blow. Your ride is light enough that turning the meth off and trying to tune it without meth might be worthy of faster times. I don't think you are making over 9psi on the 5.3. I'll email ya later today!


One of the 2 reasons I never wash my truck. (mainly it's just that I am lazy)
