Who did you have tune them? Do you still have the flow sheets for them? How did they idle?
I ran php and gear head. Idled good ibdont have the flow sheets
I dont think it matters anymore. A given nozzle size the tuner takes a well educated, conditioned guess at a pw value based on icp/rpm etc...the power changes based on injector capacity. When the capacity or ability of said injector is higher or lower it may cause the difference from one setup to another. Ive had two sets if 250/200s. Different companies. Tuning was unchanged but the truck acted totally different. Just like im guessing a 238/200 and 250/200 will probably work on the same tunes.
