So I've been tuning Gm vehicles for about 10 years now and I've been doing Chrysler vehicles now for a year.
The issue I am having is after installing a xfi 273 and a hrt2 cam in two customer vehicles I'm getting complaints that neither cam lopes like they are supposed to, and I cant figure out why because after watching videos of others cars with the same cam they all lope. All the cars I have done have a perfect idle.
I have tried changing the proportional p/n table and it hasn't helped. To be honest no matter what I do it seems the only thing I can make it do is idle hunt.
some help would be appreciated.
