Not sure when i'm at a redlight or when I start it for example, it's like it goes up and down around 700-500 or something like that I believe.. Im goin to clean the throttel body tonight but not sure if that's going to help..

I cleaned the throttle body and when I tryed to turn my car on, it barely turned on like it didn't have enough power to turn on.. So I turned it off and it wouldn't turn on again.. Like I hear something but the engine doesn't turn on.. And when I got out and locked my car the alarm sounded very low (the beep sound was a Lot lower than it was before)..!

have you tried putting your car back to all stock and seeing how it performs?

&/or

are you able to "jump" your car off? if so, do that and take it to your local parts store (Autozone, Advanced, etc) and have your electrical system checked.....or remove your battery and go have it tested

Disconnect battery for ten minutes and put it back on. It might help reset some of the craziness your car is experiencing.

Yea, the adaptive tuning needs to be
reset and relearned with the hi-po tune...
And be sure the fuel octaine rating is up
there as well to match the tune...

Define "cleaned the throttle body"....
Did you do this properly?
I have heard of 'cleaning' my TB turning i
nto 'destroyed' my TB really quick....
