Well I did a vacuum check this afternoon. Reading 5-6 inches HG. I had a few other threads bitching about my brakes since moving up here to the Mile High City. Now that I have a bigger cam I for sure don't have brakes now. Opinions needed. Torrie will be doing my tuning. Prob get a break in tune from him before hitting the dyno. Is there something wrong, maybe a restriction or cracked line or is the altitude combined with the cam really that much of a factor for the low vacuum reading? Similar set-up on the East Coast had a vacuum reading of 10-11 inches of HG. Maybe I need an electric vacuum pump. I'm all ears on this one.
