good on enrty on throttle but not off throttle

,if I can enter corner and keep in throttle about 1/4 throttle the car is good,and I can enter at a good amount of speed but if I lift all the way off gas, then tail slides up track..if I enter corner slow and lift all the way out of gas the car is good but to slow on enrty.. this is all on slick track

Need car info. 4 bar, z link 3 bar? UMP, sport mod?

4 bar ,ump mod ,metric front end ,

Gas up Lr and add compression, more brake floater angle, or your foot work isn't that great yet.
