Prior to the install of cams my car was very smooth when going from WOT to lift throttle/braking conditions. After installing cams whenever I get off the throttle my car feels like its loading up with fuel and it bucks a little bit before coasting down normally.

I primarily road race and this jerky feeling does upset the car enough to have me asking for help. What kind of tweaking do I need to do to ensure when I lift off the gas the car won't jerk me around.

Also if you feel this might be something other than tuning feel free to suggest a fix. For those about to suggest the DV, I've tried both my stocker and my JDM DV and the feeling is the same.

All I know is the jerking started the same day cams went in.

Help me out!

I had the same problem on the track. I've leaned out my low loads and it has helped.

Hmmmm.....I barely hit 60% load as it its.....what do you consider low load levels?

Well, since I'm not using the XEDE it will be a bit different. Figure out what load areas you are hitting at partial and trailing throttle and you can go from there.

You can see the tweaks I did here:

60% is high on a stock turbo w/ the XEDE. Try adjusting the 30% or lower load cells.
