Question from a newbie? I'm getting the car ready for the track for the first time and trying to get the tune-up as close as possible. It's a 850 race Holley and I started out with 80's on 4 corners, ran great at idle to partial and full throttle but thought it was running a little too rich so I went to 78's in the front and 86's in the back.... now it still run's good at idle and partial throttle but at full throttle from idle it stumbles very bad unless I launch at around 3000rpm. Is this to be expected or did I make too big of a change. Being a weekend warrior I was leaning out the front's to make it more streetable. Also I have a 2.5 PV front and rear, from reading another post I'm planning on plugging the rear PV. I know it's not an easy question to answer, but maybe one of you guy's can point me in the right direction.
