Please list anything you have done to a northstar engine to give it more power, and most importantly if you found anyone who could reprogram the computer to take better advantage of the mods. ALso list what mods gave the most benefit, etc..


I have a 99 STS with COrsa catback exhaust and K&N cone intake, no times to post because I don't have anything to measure it with :/

Two I can suggest right off the bat are Cadillac Hot Rod Fabricators (http://www.chrfab.com) and Domestic Performance (http://www.domesticperformance.com). There's others on this site- just look at the sidebars.

I guess what i'm asking is.. who has done modifications to a northstar in their car ( a deville or seville) and seen good results? I know I can get lots of stuff done at chrfab but it won't work properly in my car.... You know? :)
