vs clubsport problem

[mr_clubby96]

hey guys ive got vs clubby 5.0l and been noticing when i start it in the morning or during the avo and hold the revs to about 1,500rpm my car hunts like drop then goes up etc etc

when i hold idle to about 2,000rpm wants to drop back lower anything below 1500rpm on idle

idles fine

motor has just been rebuilt and quad throttles it hasnt been tuned etc? could this be the reason

could your un-tuned non-standard rebuilt engine be running like shit because it's trying to run using factory tune?

looks likely to me
