hm ~ ok .. my md 5/16 spacer and mrev2 is on its way home and im just so confused about if i should put them on now or later when i get the utec...
i have jwt popcharger, alpha werks headers , kinetix resonated tp's , hks ti exhuast ... so ... can i install the spacer and mrev2 first then get tune like few months after ?? i dont track the car just normally driving ..
is it bad for the engine ?? or i should wait till the utec...???

 

Put that stuff on and get the tune later, wont hurt anything

 

I just recently put on my md spacer and MREV2 and I havent done any tune yet, when you get the unit it will come with with instructions on how to install and reset your ECU, this should take care of any idle problems you have right away, however a tune later would halp you make more power from the mod but it will be ok without one. If you have any issues with install let me know but it was pretty.
