I currently have BR Stage 1 with the mail-in tune... with stage 2 on its way. Ive done some searching and never found an answer to this - how do the additional mods in stage 2 affect the integrity of the tune I acquired with stage 1? I know a custom tune is always best, but is it really necessary with these few changes?

Thanks in advance

 

the addition of the intercooler piping will not affect your tune enough to warrant a re-tune. The afr's are probably maxed out by buschur with their tune but still safe enough that you shouldnt have to worry. But another tune can only mean more POWER!

 

Save your money and do a custom tune if/when you go stage 3. IC piping is nothing to worry about and the intake pipe won't cause too much change either. You may not see a huge power gain with stage 2 but the response from the car will be nice!

 

I suspected that but just wanted to ask. Thanks for the replies!
