| ON our zf trucks, they dont benifit the same as a auto truck dose because of a few tables that limit things such as fuel delivery and rpms!! hand helt tuners dont fix this because they dont touch the tables. HTey work on the autos because the tables are already higher or filed in past 3250 rpms.
IMO EFI is way better, but its only as good as your willing to make it! AS Smokeshow said there is lots of help out there from lots of folks!
