What constitutes "heavily modified?"

[JeepHauler78]

I've got a 95 F350 7.3L. I am finishing up the manual trans swap now. It's got the 6637 intake, 3" down pipe, 4 inch exhaust, stage 1 injectors, and I will be adding an intercooler. The only time this truck will leave the garage is when it's picking something up, or with a trailer on the back of it.

So, I guess my question is...with stage 1 injectors and an intercooler, does my truck cross into the domain of "heavily modified?" It'll help out greatly when I order the chip.

I think with any injector mod it is considered heavily modified.
Look here (http://www.gopowerhungry.com/_phoenix.shtml) on the right side of the page and it says modified injectors.
hope that helps.

Actually in this case, if you aren't looking for higher-than-stock power output, you can order standard calibrations. The thing to remember is that unless you swap your PCM for a manual one (and get the corresponding manual calibrations), your check engine light will be on. For some it's not an issue though (removing the bulb works :) ).

150-160/0% injectors (commonly referred to as "stage 1" injectors) are the same as your stock AA injector but with a higher fuel capacity. With standard calibrations, the truck will run like a truck with stock injectors. You won't notice a difference until you have tuning to keep the injector solenoid energized longer.

Manual PCM is in, only thing left is lifting the ZF5 into it's final resting place.

From what I gather by your post, I would not take advantage of the full potential of the stage 1's and the intercooler without custom tunes?

I thought I saw somewhere you posted that the 120 and 140 setting were not available for the older body style 7.3's, am I correct?
I really only need econo, moderate, heavy, and very heavy tow...but a "race" setting would be fun. :) I'll probably forgo the "stock" setting since it's not my primary vehicleand get's driven maybe 7,000 miles a year...usually all at once.
