So I should be go to go with a k04 and then sending my ecu out for reprogramming?

Would I notice an increase with out the software? Or woul it be harmful to run the k904 without the software cuz I'm having the engine and turbo put in this weekend but I won't be able to send out my ecu for a few weeks

 

it'll be fine without software but you should get it chipped eventually.

 

K04 isn't worth it unless your turbo is shot. BT or nothing.

 

I've never met anyone who could form a sentence but couldn't read...
