hey guys.. new here but here is my problem..

i had on Ls trans on my b16a... bottomed out and busted the case... SOOOOO

bought a SI-R trans for it and its WAY shorter... but now vtec pops around 6.5k rather than 4.5k

how do i change it ?

btw i have OBD2.. can't find anyone who can tune it..

i'm an idiot when it comes it cars..
