[QUOTE="Don 95Vert, post: 14184471, member: 15121"] If you swapped injectors and the tune has been scaled to get under the airflow limit of the MAF curve, you need to (in this order exactly): return injector slopes and breakpoint to stock, return manifold volume to stock, return MAF curve to stock and return the engine displacement to stock. Then reload the new injector file, then the MAF values- and if you have a MAF extender then change the tune for that. Then tune away. If you use the BP modifier method for avoiding the airflow limit, then you should be OK - but keep in mind some MAF values will automatically scale things. [/QUOTE]
