I HAVE AN 06 FX4 SITTIN ON 22S WITH 33 NITTOS THE THING IS I THINK MY PROGRAMMER IS KILLIN ME, I HAVE DIABLOSPORT PROGRAMMER, AN AIR AID INTAKE, BBK 80 MM THROTTLE BODY, POWERAIR SPACER, PACESETTERS SHORTYS,CATLESS, MAGNAFLOW EXHAUST AND E FANS AND I THINK THE TRUCK RUNS LIKE CRAP, IVE CONTACTED DIABLO SPORT AND THE ONLY THING THEY RECOMMEND WAS A CUSTOM TUNE!!!!!!!!!!!!!IF I KAN PLEASE GET SOME TIPS ON WHAT UPSHIFTS TO PUT OR MAYBE THE WOT FUELTABLES AND SPARK ADVANCES, THANKS IN ADVANCE

 

1. Look at your keyboard.
2. On the far left side, there's a key marked "Caps Lock".
3. Press it.
4. Thank you.

 

Can you define "CRAP"? What is it exactly doing? The more you can describe the problem the better the response you are going to get. Does it run better when you return it back to stock?

 

its very sluggish at take off

 

What revision is your Predator on?

Are you running the 'Airaid tune'?

If not, please make sure the unit is up to date (9r08) and load the Airaid tune, I think you will be pleasantly surprised at how the truck picks up!

 

latest 9r08, i just updated it bout month ago, truck is still the same

 

If you check options/show last tune written, what does it say?

 

Role,
I would say you have an issue either with your programmer or with you truck because the new 9r08 update on my truck makes it a hot rod on 35's. Good luck and enjoy when you get her fixed up.

 

i guess it is my programmer, kause i tried an sct yesterday and it really woke the truck up

 

Did you ever get around to making sure you had the correct tune installed with the Predator?

 

yeah i checked

what r the upshifts 4, i guess thats whats killin me

 

Upshift MPH and RPM?

Those would be adjustable parameters to change your WOT upshifts.

 

well there's your problem, for real i think your getting some turbulence after the throttle body, try taking the spacer out, what i think is happening is, is that the spacer is smaller then 80mm and choking your trucks intake at part throttle. try it should only take 10mins to take off, and if i'm right there will be a world of difference.

 

Hello.

No sir, I don't think this is the problem.

On or off, a TB spacer makes no difference whatsoever. Absolutely none, save for a whistling sound perhaps. Redneck turbo

I'm assuming it's the correct diameter - I'm giving the OP some credit here - but even if it isn't, at part-throttle the flow requirements are less so this will not be a factor anyway. And - pleny of turbulence already by that partially closed throttle plate, lol.

OP - good luck.

Do you know what rear end you have in that truck, i.e 3.55, 3.73, etc...

You can find a thousand posts on the site recommending a gear swap when you go with 30" plus tires. Was your performance lagging prior to the programmer?

Like MGDFan said, while useless, the TB spacer is not the issue. Not sure what you can configure with the Diablo sport but good luck man.
