so I think the mpg gains listed on every other part is a joke or someone should be able to get mpgs to 30-35. 1-2 mpg adds up on paper and fast but not in reality, or the gains don't fully compound into real gains because other modifications are overwriting the gains it is supposed to provide because the mod tested is just going on a bone stock truck they are testing with just that one additional part? I mean base of like 15 mpg 2-3 mpg from injectors 2-3 from upgraded turbo 1-2 from airfilter and intake even the overflow valve said mpg gains on it, same with exhaust ect. I've heard 3 from mpg water meth and deleting the fan for electric ones is supposed to give huge boosts i mean these adds are definably not compounding in my truck. or do you have to reduce fueling along with modification to see changes? Don't ever hear people wanting to go with a plate to reduce fueling beyond stock. I've hear of people doing some pretty ghetto hydrogen fuel cells to boost mpg too! But 500hp+ is crap load of modding to any year of this era of dodge. At leased done right, which i am gonna assume your not running a stock tranny, so I am guessing a small house could be bought with that investment! I am probably at 250-300hp with these new injectors and everything i got done but stock afc. Nearly half hah! How much horses are you pushing/pulling with manonbroke.I could make a graph on fuel mileage in relation to hp might peak somewhere throughout would be hard to make it consistent with so many different mods and to gather that data.

my engine is a 215 .... with the big exhaust,afc mods FF plate,tires, low stall,timing,bhaf, Synthetic oil..... I'm not seei.g 17.8 city ..... figure around 260 hp ... now ..

pull the plate after studs, more timing,twin ram.... 300 all day no issue .... add a second turbo .. S400 to the hx , and some 75 sticks , and bang into the 400's easy ....... :tu:

Ok so the injectors really made a huge difference, these puppys smoke without adding much! DAP all the way even rebuilt! pulled the injector return line and put the new banjo in it and whoola! perfect! This one has two orifices on it and they are also more of an cone not a single perfect circle cylinder hole like the stock 10mm banjos. MY 12mm banjo on the return line also needs a new washer got the cummins part # and going to the store tommorrow to get it, the T from my raptor return fuel line was missing the bottom one. These injectors also cured all my white smoke other then super high rpms with out load or cold start! So timing is it! Thanks for the help everyone! This forum has saved my life! years of experience in a few minutes/seconds.

Yeah Prineville! Madras has a track too which is 35 minutes away from here too! Well if your ever down here visiting write me a message we can always go see when if there is a open race night or something sucks its hitting winter soon and might be close up if it gets bad or just seasonally open.
