then it needs a tune...that's all that is...i garuntee there is nothing wrong with the motor...nothing is working good with each other thats why your getting the weird idle and its running funny. a tune will smooth everything out and correct all issues

if it's the set up he told me it was then it doesn't need a tune. Yes all built cars even stock setups need/use tunes. But the setup he told me should not require a tune to idle good and shit.
