I have a new Chevy pickup with a 6.0 Gas motor. I put duals with 3 1/2 inch pipes and a K&N intake kit on it. I was told to also change the chip. Is that a good idea and if so what chip company will be the best without hurting my motor.

Thanks Bob

Please describe your exhuast system in more detail. I hope you're just talking about 3.5" tips...

I would skip a chip, they usually require premium gas.

A chip will improve power but does require premium fuel. I know where benwantland is headed. A too big exhaust system will hurt power not improve it.

dittio with the large exhaust, the new cars & trucks have a built-in chip that needs a programmer sold at most catalog and parts stores to re-program the computer.
Plus you need to open up the breathing to help any performance.

I hope you mean 3 1/2" tips. 2 1/4" is about all you need. A single 3.5" pipe would work. But 3 1/2 duals are to big.

For computer reprogrammers check out Jet Performance.

Just about every chip or programmer on the market changes the timing and increases the fuel mixture. This in return makes more power and requires premium (93octane) due to the increased timing. If you find a chip that doesn't require premium fuel it probably doesn't gain very much power. :nono:

When you buy the Jet programmer you can chose between a setting that allows you to run 87 or 93. You can program back and fourth if you get tired of paying for high test, it will even program you stock settings back in.

Hypertech also carries a line of programmers for most late model trucks and cars.
