I bought a Diablo chip for my 99 5.4L Off road.
Power was alright but the down shifting was harsh from 2nd to 1st, my tranny would get a big clunk sound.
Also, the redline was not changed.

I returned it for a Superchip that I have not yet recived, I was wondering if anyone could shed some light with thier Superchip experiences.

 

RPM shifts are around 5300 on each gear, Did gain some down shift response, pulls harder from mid rpm to about 4900 rpm. Still won't run as good as the Chevys

 

That transmission shift is a "Ford thing" I have it in mine too, the superchip made it mostly go away but it still seems to "slip" a little.

And if you don't mind spending around 3-4 thousand dollars more go for the Chevy, I still love my Ford.

By the way BBRANJEN why don't you just sell yours and get a Chevy, you talk crap about Ford all the time but you still drive a Ford???

 

Hi ****,

We carry both products, our customers prefer the Superchip, as do we.

As another poster mentioned, getting a little clunk on the light throttle 2-1 downshift happens in these transmissions, ours did it stock too, it's not been anything to worry about with ours, or our customers. We have several 150's here at Performance, all chipped, & some heavily modified.

Your "redline" is *never* going to change with any chip, as that is determined by the design of & conponents inside the engine. You might actually be referring to the Top Speed Limiter, perhaps? The Superchip removes that. Or, you might be referring to the WOT (wide-open throttle) upshift point in the automatic, which we set for quickest acceleration. Or, you may be referring to the absolute rev limiter, which should always be left in place (though may be slightly raised in some applications).

At any rate, good luck!

 

On my 01 Lightning, after I instaled a Diablo chip, My shift point max went from about 5000 RPM's to about 5400RPM's. But my L still had pull in the uper RPM range unlike My 4x4.
Up shifts are super hard even under normal exceleration but down shift's are unchanged.

That's why I was wondering if my Off road's max shift point would change also.

Also, will a cat back and a intake effect my Superchip?

 

Don't believe you will need a chip reburn for those two mods.

Hi ****4,

Actually, your factory stock upshift point @ WOT in any 1999 or newer Lightning is 5250 rpm, you can use that figure to check the accuracy of your Lightning tach, at that specific point anyway.

So that means that in reality, you're actually turning about 5600 rpm on your WOT upshift in the Lightning with that chip, and that is not unreasonable for the Lightning, that's OK.

One thing we do not like in the Diablo chip for the Lightning is that it cranks the line pressure up so high to make it shift very hard, and that causes accelerated wear & tear on the transmission's pump. As soon as I felt what it did in our 2001 Lightning, it came right out.

Cranking up the line pressure that high in the program is *not* the safe long-term way to get a "hard" upshift, anyone that wants that hard an upshift should effect that with mechanical modifications to the transmission, so that you don't cause premature wear on the pump. Some guys rave about how hard the Diablo chip makes the Lightning tranny shift (and I like a nice stiff upshift too, at heavier throttle), and we could easily do that in the Superchip too, but won't, as it's not good for the pump long-term.

On your regular F-150 with the ORP (Offroad package), your WOT upshift points will be raised with either the Diablo or the Superchip, to anywhere from about 5200 to a max of about 5400 rpm, it just depends on the vehicle's configuration & it's particular computer code. The heaviest trucks will have a bit lower WOT upshift point, for example.

In the regular F-150 and in the Lightning, you do not need to have the Superchip reprogrammed for things like a K&N air filter, or an airbox elimination kit (as long as it's not a "ram air" kit, those *do* have to be tuned for to fix the A/F's) or a cat-back exhaust. Custom programming is generally required in these vehicles when you do things like change the MAF (mass airflow meter), or do major mods like supercharging, nitrous, ported heads, camshaft changes, etc., as a loose & general "rule."

If you have any questions about any of this, or would like to go over in more detail, please feel free to give us a call.

Good luck with your trucks!

 

As of last week I sent my Diablo chip to 2D's Performance to have it reprogramed so the shifting isn't so harsh. Also my program is 8 months old, and they said they had a updated version which is better.

I have also heard that the super hard shifts at red line can trip the L's supercharger to shut down for a split second.

Should of bought a superchip from the begining.

 

Hi **** 4,

Hey, you have to deal with what you have, and that's OK.

It's actually not the "super-hard" shifts that cause the boost to drop, that is actually a completely different but related issue that requires a minor mechanical fix to do it right. We can take care of that for you, and you can still use your existing Diablo chip with this, just give us a shout & we'll go over that with you.

There is a mode that will dump boost if certain conditions are met during a full-throttle upshift. The drag racers all found this out pretty quickly, and we have a very inexpensive kit that will take care of that for you, so you can get the best possible ET's.

Hang in there & good luck!

 

I have a super chip in my Lightning Best mod yet
