Aggressive CAM, parking lot driving smoothing out?
I am all new to this world of big power as just got my car, but I have one thing that is on my mind at the moment.
My Z has a big cam in it ,very aggressive idle and I am wondering if I can tune the low RPM low speed behaviour of the car? It has been tuned apparently but maybe not so much for low RPM low speed.
I am trying to find out the CAM specs, but what is happening is if driving down side streets or parking lots at slow speed the car becomes jerky, like foot on gas and off gas constantly the forward and back jerky feeling.
If I am in first gear and raise the RPM (1500+) it settles down and smooths out.But let go of the gas pedal it starts bouncing back and forth. I can soften it out by pushing the clutch in a little and giving some gas, especially when trying to park the car. It will want to stall if left in 1st and no gas to get at least 1500rpm.
I understand this is the draw back with having an aggressive CAM, but wondering if it can be smoothed out a little in the right tuning hands?
This is not my daily driver just a weekend car at best but if possible would love to smooth it out a little.

It can be fixed, I would highly recommend finding a well know tuner in your area. Where are you located? I am by no means a professional tuner, but i do have some experience with it. My most recent tune was a grand sport with a BTR stage 4 and could idle around a parking lot in first and second gear, foot off the clutch and gas and it would cruise around at 5-10 mph

Any articles online that would outline what is needed to be done and what tables for this low RPM fix?

If you have a big cam you generally put different gearing in the rearend. 3.73, 3.90, 4.10s would work nicely.
