I have a 2004 Chevy Silverado and a friend tried to put a SuperChip programmer on it and after he reset it to the factory setting, it has been idling low and stalling out. He said it would take a few days to the computer to realize what is going on. Is this correct? Do i need to reset my computer or get a factory tune from a dealer/mechanic?

Question edited for clarity.
Question moved to model category.

Resetting the airbag light on your Chevy Silverado should be easy to do. Follow this video to watch it being done in a Chevy Silverado. To start with, you will:

• Put the key into the ignition
• Turn the key to the "on" position
• Wait for the airbag light to turn on
• Wait to continue until the airbag light turns off (around seven seconds)
• Repeat the same steps twice more
• Turn on your engine

After you take these steps, your airbag light should turn off. If it doesn't do so, then you should consider taking your vehicle in for diagnostic testing.

If the airbag light remains on, it could mean that something in the system is faulty. That could mean the airbag, the computer wiring, or another issue. Oftentimes, when the airbag light comes on unexpectedly, it is because of interference with the switch.

Always use stock type plugs,that what there called for,some vehicles like yours don't run good on other types.They come set at factory,I always check gap and they are always right.As they say,it ain't broke don't fix it.

thats interesting, I plan on putting a HP CHIP in my 87 buick GN, but I know its not good to put super chip in, not intended for street vehicles. maybe its telling you to tone it down, maybe its telling you your engine may not handle this upgrade. or its not cpmpatable ! I would contact the manufactorer about this, they have a 1-800-number for tech questions . let me know

Recheck your firing order for basics. If this is in good, a compression test may be necessary. Which enigine do you have?

Hello. your best choice at this point, is take the truck to your local dealer and have them upload the factory software to the engine control module. the dealer is the only place you will be able to get the factory software. it is not uncommon to see a programing error in the middle of programming. the dealer will charge somewherebetwwen $50.00 and $100.00 to load the factory software

I tried the hypertech for my 2004 Silverado and it would not accept the programming so I returned it and got a Superchip programmer. I loved what it did for my truck. I maxed out everything which included the performance setting that requires 9 octane, I increased the 1-4 shift points by 500rpm each, I increased all the shift pressures for 1-4 gears and I eliminated the speed regulator. They claim 10% more HP and 13% more torque and they speak the truth. I also had a K&N intake and filter and a 2 chamber Flowmaster muffler with the exhaust cut off at the axle. It sounded so mean and it was significantly faster and more responsive. The most important thing to change is the shift pressures which will not only make each shift more solid and tight but it will extend the life of your transmission. They are set to slip from the factory to make the shifts smoother and longer which puts excessive wear on the transmission. My truck was a regular cab 5.3L with light duty power package that included the G85 option (locking differential. I use it as my profile picture. I traded it in on a Trailblazer SS but I wish I still had it. You have to understand that trucks are designed to haul things and the aerodynamics are not streamlined like a car so they play a huge part in limiting a trucks top speed and acceleration. The intake will help increase your low end (torque) and the exhaust will help with the top end and help the engine tach up a little higher. The power programmer will make them all work together beautifully. You can all 3 for around $800 and you won't run the chance of destroying your motor. I also noticed a gas mileage increase along with more power. You can't beat that combination. Please rate me on this answer.

this code is for the electronic throttle. do you have the factory wiring harness? had some problems with connectors might wanna look at that and maybe replace connector

Are both batteries fully charged showing 12v? I ask this because I don't know if your friend's vehicle was charging. If it wasn't then when you put that battery back in your system it would reduce your overall voltage.

Can you contact the superchip programmer help line?

Read the car manual, in the page were it shows the dashboard fuse panel find the radio fuse pull it out and put it back in with the fuse tool. This resets your radio, it did the trick for me with.
Just make sure if you disable the radio security lock if it enabled before you pull the fuse. It may lock you out, all the information is in the manual.
Good luck and hope this helps.
