I'm installing a full TBE and will get the tune/flash later. since the AFR is still set @ stock settings is it harmful to rev the car before getting a tune? I hear I shouldn't rev past 3500 until I get the tune. or can I still rev it time to time , just don't over do it?

editops meant to post in Evo IX section...

 

youll be fine, i wouldnt suggest racing all day and redlining but daily driving and such is fine, but definately get a tune... go to mellontuning and get a tune, the best mail in flash there is and youll notice evne more power

 

With just a tbe youll be fine. Get a tune when you can, but with just a tbe, you wont blow your motor if you drive hard, not even close.

 

in the evo x section??

 

yeah this is placed in the wrong section but other than that I am running the exact same thing you are for 2 weeks now. In jersey so whenever it drops below 40 F at night I overboost if i punch it too hard. Sucks cuz then my SES light goes on. Gotta get a tune as soon as I put everything else in.
