i have recieved my vortec heads and lower intake and now i am choosing my cam and curious about how tuning for the zz4 cam and the hot cam .. how many headaches does the lower vacuum at the map sensor from the hot cam cause in part throttle tuning?
what tables are more effective at changing on a speed density car with this combo ??
thanxs for help mike

 

On my setup, I needed less fuel on the lowend/idle and more thru the mid/topend rpms. Read Tim's PE tuning post at the top of the page it goes onto some detail, that should get you off to a good start.

 

thanxs for the reply
i read the article after i posted and that helped greatly
