Careful. The 'chips' you see on ebay tend to be resistors to change the intake air value to a permanent 'low' temp instead of reading off the temp sensor.

Wester's Garage and other places do offer custom calibrations for the FWD northstar. Example: http://www.exatorq.com/CadillacNorthstar

Your car doesn't use a 'chip'; the PCM has to be re-programmed.

Bruce is right. They'll do more harm than good. A 5-10 MPG increase is laughable.

Bruce is right, and on a stock motor every performance chip has produced stock performance... Unless you are planing on making internal modifications to the motor, like new cams or ported heads, or higher compression, then these chips do nothing.

Oh and our transmission is rated for 300HP... make 305 and it seems to live about 10 minutes... I know, I'm on my second.

I broke down and tried one of those ebay chips. Basically my car idled really high, about 2500 rpm, and burned rich, neither of which increased my power or gas mileage. It was so bad I could get up to 50 mph inside half a mile without touching the gas, and I had to ride the brake to keep from speeding. I'm just glad I didn't do any damage to my car.


No matter where you go, there you are.

If it sounds too good to be true, it usually is. We tried to warn you, but sometimes you just have to find out for yourself. Thanks for the feedback.
