Default Anyone running HPP3 after header install

Is anyone running HPP3 after a header install? My thoughts are this.....Headers tend to cause a car to run rich and HPP3 tends to lean a car way out.

So would the two cancel each other out and give you an optimal tune? I know it's crude and doesn't work as well as using LS1 Edit but is my theory flawed?

my headers caused me to run lean... and I concur... HPP3=useless (unless you can get it for under 100 bux and all you want to do is adjust shift points and gearing/tires)

I wouldn't bother with LS1 Edit either... HP Tuners (www.hptuners.com) is the best full featured tuning software available for LS1s
