Default a few FI problems

I installed the ECS Paxton 600 kit about a week ago and am having a few issues,

i got the starter tune from ECS and understand that i need a dyno tune before it will run perfect but right now my car is acting up. when i start off in first gear there is a delay and the rpms drop to 500 or lower like it wants to die, i have to raise the rpms just to keep it from dieing on me. also when i put the clutch in to brake the rpms drop considerably before leveling out. on top of this i have a heavy tick from the drivers side of my engine that im pretty sure is an exhaust leak from the headers but not 100%
when i sent my pcm in to be tuned i let them know that i have long tubes but i am still getting a check engine light for my rear drivers side o2 sensor when i believe they should of been deleted in the tune, makes me think the tune didnt stick or something happened which would be bad because i have been driving with 60# injectors. any ideas? im getting a dyno very shortly but im afraid to drive it there for these reasons

thanks in advance.

Don't assume it's the tune. Make sure all of your hoses are tight and you have no boost / vacuum leaks. You are taking it to have it tuned at the dyno and not just dynoing it right??

You need a good street tune well before you need a dyno tune.

Is it a load-bearing dyno?
