After tuning my car on the dyno with 0,0 cam angles I still couldn't get the car to idle when it got to a normal temp! I called crower and the tech told me to go -1 int and +1 on exh. and now the car idles but I need to go back to the dyno to remap the a/f ratio and timing table!!

I no this reduced the amount of overlap but what does it affect the cams perfromance??? Good or bad???

Thnaks

 

I typed this post at work very quickly and it came out in mest up english LOL

What I 'm trying to find out before I go on the dyno is what effects will -1 int and +1 exh. have on the performance of my crower 404 cams???

11.2:1 comp. with crane valve springs + retainers
