Yes I've seen the post about it and off the shelf chips...But no one bothers to explain why they are useless..All they say is "dont waste your money" or "it doesnt work" Anyone actully have one and not just say what everybody else is saying?

I have a chip i noticed a little better throtle response and it got rid of my govener but thats about it i paid 40 dollars for the chip its a FAST CHIP stage 2 but personaly if it was not 40 bucks but 200 like they sell for i would say its not worth it.

Slayer isn't referring to a chip, he's referring to a little useless junk gadget that tells the ECU your throttle is further open than it really is. The benefits of such a device include:

a larger (oversized) pump shot, which can cause bogging
a little extra part throttle spark advancement
quicker entry into PE mode, degrading fuel milage...

Regardless of how they may make your car 'feel' faster in partial throttle, their benefits are utterly worthless. If you want more performance from that route, save yourself some cash, press the pedal more, and get the benefit of extra air at the same time

Well I already have a modified intake (K&N Filter) and modified exhaust (Dynomax catback,catco cat) I dont think the extra fuel will rwally hurt it.I think i might buy it.

FAST RS

The extra fuel will kill your CAT i had my IAT set to think it was awalys about 28 degrees out side so it would put out more fuel and it ended up killing my new cat the thing was destroyed inside after a year. Also didnt notice much of a difference in power.

V8 Slayer

But if thats the case you can say,if its cold outside dont drive your car because it will kill the cat...or dont modify the cars computer because the extra fuel will kill the cat.

FAST RS

True im just sayin what happend it could of been a defective cat but the problem occured after i did that. I changed it back to the stock sensor and put a new cat in and have not had any problems in 3 years.

if a chip is $200 and does not do that much, why not just spend $300 to get the supplies to do your own prom burning?

V8 Slayer

Because I dont have the equipment nor the knowledge of even where to start and cant just go experimenting on chips or the time....

TechSmurf

I'd continue, but the ignorance overwhelms me. It's not worth it. If you're gonna do it, get it over with so I can laugh, shake my head, and resume wondering why I bother in the first place.

Actully...I decided on a Superchip for my car.I found a local retailer and it will only be about $100 with a 30 day money back guarantee.So if you guys are right and I dont see any gains or lose gains.Back it goes....The computer is under the passenger dash right?

Actually no.

When it's actually colder, then more fuel will be fed to the engine. BUT, when it's actually colder then the air will also be more dense, there fore the extra fuel will be burned -> The cat is not affected because the mixture is not overly rich and a load of unburned fuel does not reach the cat.

I don't have one, though I have known of a few pople who did. They all agree it was a waste of money, with no change at all in ET or MPH, and no noticeable difference anywhere else.

I totally agree; the guys on the PROM board are more than willing to help. Heck even their sticky at the top of the forum explains it all. That's what I'm holding off on; as soon as the car is otherwise finished (trans rebuild, engine rebuild, interior rebuild, exterior rebuild, AUGH!), that's when I'm picking up the PROM burning stuff...

I had an ADS Superchip in my car; took it out, noticed NO difference. The car even seemed a little stronger with the factory chip back in.

I wonder if you have a speed shop nearby that would burn a custom chip for you... and how much it might cost. Couldn't hurt to call around.

would tricking the computer into thinking the throttle was open more retard the timing?

TomP

If you're tricking the computer, who knows what could happen.

i have never heard anyone say anything good about over the counter chips, i told my dad i might be getting into prom burning and he asked why i don't go buy a chip. i was thinking "for a v6, does anyone even sell them?"

besides, then everytime i wanted to change somthing i would need to spend another $100.
