[QUOTE="Charles, post: 980953, member: 103"] Anyone running a DPC421 PCM could take a handful of files I have sitting on my laptop and be doing rolling burnouts and dragging trailers all around no problem with a 200 EDM. If one truck runs crystal clear on a file and another is a smoky pile, then there's not a tuning problem, there's something wrong with the second truck. When I put the 300/100's in my 550 it was otherwise bone stock. Stock charger, stock everything but injectors and a downpipe. A good running file from my red truck ran identical in the 550. Same cache code, same injector, same result. If the file's good, it's good. If not, then it's bad, and with anything 200 and up on nozzle, it's usually real bad. With a 4/4, the difference between super clean and super responsive vs a total miserable failure can be as little as 0.2ms either way. You have to keep ICP out in front of pw. But since both are determined by MFD, which is your right foot, if the relationship between pw, ICP and MFD errs in the favor of pw as you're coming up on the pedal, then you can drive all day long and never get "on top" of the pw. Truck smokes, has low power, won't lug, drops on shifts, won't even touch a single charger, so on and so forth. And most times pulling just a few fractions of pw as the MFD is climbing will get the ICP out ahead and pull a complete 180 on the engine's feel, output and smoke. I tried to say it before, and I'll try again, if it's off a little, a bigger nozzle will tell on you. And it will be BAD. Like real, real, bad to drive. Basically ruin the truck. No doubt. And that is exactly what is happening to anyone who ever says they don't like a 200 EDM. Because if a 200 is dialed, nobody on planet earth wouldn't love the way it drives. And for seat time on a new setup, yes. It takes some time. I would say after I had the 200's dialed, from there to the 300's took a couple days worth of pulling over every now and then during the course of normal daily driving and making some ICP/pw/timing changes until the pedal tip-in was good, pedal was linear, and the ICP to PW relationship was good with good timing. For more complicated needs it takes more time. I probably have 100 files for the 550, each one being a small change, continually working toward a goal of full power with an unbreakable 1250 degree EGT ceiling. Some of that was that half the files were on a stock charger, then the rest at a higher output with the 38R still under the 1250 degree ceiling at all operating points, even dragged all the way down to stall flat to the floor. I'll say again, if I didn't already have a file for a given setup, and wouldn't be able to sit in the truck for a half-day and make sure it was crisp, then I wouldn't go over a 200. I fail to see how professional tuners can't have canned programs for a 200 written for basically any practical setup at this point. If you write the file for a single charger on a stock pump, you'll be good to go down the road clean and clear on any other setup that isn't having it's own issues, which won't run right on [i]any[/i] injector anyway. Although they will almost always run worse on a faster injector as it highlights the errors. What is a 200? Like a 0.011? In 2014 surely we can get past mainstreaming tuning for a little guy like that. In the grand scheme, the biggest nozzles available are small. [/QUOTE]
