Performance Chip

The biggest change you will feel is in the shifting, mainly the 1-2 shift, but all the shifts are firmer. Additionally the shift points are higher as well. I noticed a little more low end torque as well, using the butt dyno. But over all one of the best mods I have made to date.

The stealership shouldn't be able to do anything to you, even if you do have the chip. Being a bunch of slick bastards, though, they probably will come up with some way to screw you. I think if you pull the chip out and reset the PCM, they won't know the difference.
BTW, none of the chips are going to give you more than a couple HP and TQ. This has been verified on the dyno. IMO, it's still worth it just for the firmer shifts.

·In previous threads it was always stated that it will actually help preserve your transmission by making firmer, quicker shifts thus reducing the heat produced by each shift, which means, generally speaking it should last longer.

·You will gain firmer, faster shifts, higher shift points ( the car will shift to the next gear at a higher RPM at WOT), downshifting will be attained higher in the RPM range, and the car will feel a little faster.
As far as it being faster, at least in the 1/4 mile, it's not. At least mine wasn't. I ran a 17.6xx with or without the chip.
The car feels faster because of the shift points changing. It's still worth it for the shifting, just don't go all out and get a multi position switched unit that has all sorts of programming. A single unit will do just fine.

I liked the chip, but the firm shifts did get a little tiresome after awhile. It was cool chirping 2nd with sticky tires though. I didnt gain any ET from it, but I think with better racing conditions it maybe would have cut off a tenth or two just from shifting faster. The 1-2 shift is sooooo slooooow at WOT that it has to be hurting the ET.

The next mod to my car i want to do is a chip. I have the vulcan with ffv. Do yall think the ffv will get in the way of chipping it? Also, will the chip raise the rev limiter and take off the top speed limiter? What injectors could i use after I got the chip? What kind/size? Thanks a mill.
Ask a few programmers about the the rev limiter and speed limiter. I know my superchips chip got rid of my speed limiter and it shifts higer, too. But that's a gen 3 duratec, not a gen 4 FFV, so who knows.
If you have the FFV, I don't think you'll need to change injectors, but if you really wanted to you should do it before you get the chip so the programmer can accomodate the higher flow rates. Basically, I'd suggest getting the chip as your last mod so the the programmer can optimize all the mods you've done. And you won't have to get it reprogrammed if you decide to do more mods, that is if you waited and got the chip as your final modification.
Faster gear changes also mean that the clutch packs slip less and therefore wear less.
I might want to firm up the shifts a little, but not so much that it would get annoying. Is this adjustable by a tech?
Is there any permanent damage to the engine or drive train if the Rev limiter kicks in? I might want to keep the rev limiter, lose or raise the speed limiter, and get higher WOT shift points.
What is redline for a factory '02 DurTech 24V?

Also, would a chip shorten the wait or delay to intiate a 2nd -> 1st downshift when selecting WOT?
Currently, at almost *any* cruise speed, making the jump to hyper space is almost as bad as the Mellinnium Falcon-- you hit the pedal, wait, the car is thinking... thinking... and decides to launch.
If you're already under acceleration, no problem. But from any cruising speed (in OD) it's as though a committee needs to decide if this is appropriate.
OK, I realize a computer is doing just that, but what is it-- a 286 on 8MB RAM?
Quicker throttle response in the 2->1 area would be too cool.

The major reason for losing the rev limiter isn't to be able to go over it. It is to stop the fuel cut programmed into the factory computer. I need the limiter removed on my car because when I run nitrous the revs get to 5500 really fast and if you don't let off fast enough or the transmission lags then the computer cuts fuel and you go lean which can cause damage.
I don't think I will bother with a chip. I need the change on the fly abilty of a tuner. And my 1-2 shift is probably firmer then everyone who has a chip.

Most tuners can do everything that a chip can do.
