FF 250/200 questions

[lincolnlocker]

Going to a 250/200 injector..... does anyone expect tuning to be spot on the very first try?

Extremely small variances in tuning can yield drastically different results on large injectors/nozzles. In the way it runs, sounds, etc.... all will be affected.

Unless the truck has been live tuned, or there has been significant number of tunes and data logs emailed back and forth between the truck owner and tuner of choice, don't expect them to run properly right out the gate.

Just to get this part aired: If there were existing issues with the truck prior to the injector swap (known or unknown), expect them to be magnified. If there are injector issues, expect them to be magnified with larger injectors/nozzles.

There is a whole host of things that could be happening. First thing first, talk to the person tuning the truck. And I don't mean just call to complain, I mean gather some data logs, and sit down on the phone and have a very long, meaningful conversation addressing all aspects of how the truck is performing with each and every tune variance.

Anyone that does tuning for a living reading this, PM me for my personal home address to mail a check and thank you letter to....... LOL LOL LOL

good post sir! that should be a sticky somewhere for those who haven't delt with tuning or injectors...

Soooo any answers to the actual questions

no

possibly


no

Been running these for about two weeks now on gearhead tunes. Running the factory hpop at the moment which gearhead was supposed to tune for as I wasn't ready to upgrade it along with studs. My previous setup were swamps 176/146 with David's tuning as well.

With the swamps setup I was getting 18mpg on the highway. With my current setup I'm getting 9mpg.

The FF injectors are noticeably louder then the swamps were.

Truck runs great in the tow/economy tune, feels and sounds like crap in the street and all out tunes, no peddle response and less power.

Truck felt more responsive with the swamps injectors and more powerful.


Are these injectors normally loud?

Can my issues be due to the hpop?

Is the mpg typical?

No idea where to start with the tuning as gearhead is out to sema.

Thanks for any insight guys.

Matt tunes for a stock throttle feel. You have to get over 50% throttle for the fun to kick in. Lot's of other tuners make the throttle more responsive, which feels like you have more power, but you actually run out of usable power earlier. Even now, back with my 250/100's (using a chip tuned for 400/200's), I can get sideways in a hurry when I stand on the throttle in DD or race tunes.

Matt, like every other tuner I've dealt with, will stay on the phone with you for as long as it takes (and as many calls as it takes) to sort through your issues.

I'm hoping so because the economy tune isn't economy friendly and is the only one performing right now. This truck used to tip with the 175/146 setup and I was hoping to improve on that.

In my case i will blame the injector builder. Was live tuned and two different tuners couldn't get it right. One said "its not in the tuning, evidence points to an injector." So i went with a different set and love them. Smooth and responsive. PIS builds a good injector and will have my business in the future.
